  1. Okay, so here's the prototype for the rack mounted Stomp parameter controller I said I was planning. What I have here is the parameter controller and a foot controller sending MIDI over USB, and a Raspberry Pi running as a USB MIDI Thru box linking everything, including the Stomp, together. Parameter controller and foot controller are based on a Teensy boards which provide easy USB MIDI capabilities. Teensy LC currently used, but the parameter controller needs a Teensy 3.2 to provide enough RAM to allow me to support multiple Stomp programs as I've currently run out of memory for the arrays of strings I need for the "labels" for the parameters. I could work out a more efficient way of doing it, but I think it would still be marginal as there are a few more improvements I could make. The parameter controller uses rotary encoders to change the values of the Stomp parameters I want to control. For each Stomp program I have one page for the Amp parameters (typically Gain, Bass, Mids, Treble, Master Volume and Channel Volume) and one for a single stomp, so usually an overdrive. I've also put a Tilt block in each Stomp program and that's accessible on the Amp page so that I can try making quick overall changes on the fly with one button, or perhaps link that to switches on the foot controller. Display is via a Nextion, and that also supports buttons for swapping between Amp and Stomp pages, saving of the current parameter settings, or reset of the current settings to those saved. On power up the controller reads in all parameters from EEPROM, and sends them to the HX Stomp for the currently selected program. Changing a parameter immediately changes the value on the Stomp, but nothing is "saved" until you explicitly select "Save", whereupon the values are stored permanently on EEPROM. Obviously when I say save I mean saved in the controller, not the Stomp. Changing the program on the stomp results in the current in-memory parameter set for the program being sent to the Stomp. In this way I can tweak the parameters and change back and forth between programs without losing the changes I've made. If I want to discard the changes I can use "Reset" to replace them with the set stored on EEPROM. The foot controller is pretty basic at the moment - I've set it to give me tuner on the lower left, program up and down on the right, and the top left toggles a 20dB boost on and off for when I want to use the Stomp to drive a power amp. I'm planning to replace this with a six switch version with another Nextion display to show what each switch is doing. The code all needs some work, and is pretty amateur (monolithic, global variables, etc.), but it's been 25 years since I did any coding in any serious capacity and I've forgotten almost everything I ever knew! Raspberry Pi MIDI Thru from here: https://neuma.studio/rpi-as-midi-host.html I used a more recent set of instructions for making the Pi read-only: https://medium.com/@andreas.schallwig/how-to-make-your-raspberry-pi-file-system-read-only-raspbian-stretch-80c0f7be7353 Next steps are the rack mount version and a 3d printed box for the larger foot controller - but that's going to be a while yet.
  2. The way I look at it is this - compared the number of people who play bass in some form (or whatever other instrument) the number of YouTube "stars" is probably a minute fraction of that number, and largely people who are either doing it as a job or are spending the same amount of time on it as they would if it were a job. The fact that there seems to be a relatively large amount is because you (and everyone else) happen to be coming across them in searches, and they're coming up in those searches because YouTube etc. gives them exposure that they couldn't possibly have had in the past. The fact that they are relatively popular is because there are a lot of people interested in the same instrument. Now, most of us have (or will have had in the past) day jobs, and most of us will be pretty good at those jobs. Some of those jobs will be highly skilled - there's probably a fair smattering of doctors, surgeons, lawyers, etc. on this forum, and all manner of other skilled people. If amateur "lawyering" or amateur surgery were a thing (okay, I know it probably is!) then there might be a load of really accomplished lawyers and surgeons posting videos of their skills on YouTube, and eager amateurs sucking it up, learning how to do a neat bit of litigation and a tidy appendectomy. I guess what I'm trying to say is that most of us have skills which we've developed with the investment of a huge amount of time, and for most of us that will be through our jobs/careers as that's the only opportunity for investing that much time. They may not be "sexy" skills, but nobody should be feeling inadequate about not being able to develop "sexy" skills because the vast majority of us don't have the opportunity to invest the time. I may, of course, be talking complete tosh - it has been known...
  3. Similar here. Mid 20s singer, mid 60s drummer. Guitarist mid to late 30s and myself and keys are in our 50s. We all like the music we play, and we get on well enough socially, so it’s all good.
  4. As far as I can see the Stomp only sends program change messages, and can't be configured to send CC. I don't have any knowledge of the C4 so I can't comment on whether it would do it the other way. If it did, however, and if you were up for a little bit of DIY, I've recently come across this which I'm successfully using as a USB MIDI hub to control a Stomp from other MIDI devices: https://neuma.studio/rpi-as-midi-host.html.
  5. I’m thinking hard about getting a 3D printer. @stoo, what material did you use for the case - I’m wondering whether PLA would be strong enough or whether it would have to be ABS?
  6. No, afraid not. Partly because it isn't built yet, and mainly because I'm awful at documenting stuff. I'd be embarrassed about my shonky code too! I have been doing a bit of tinkering, however, and I'm fairly certain I've variously got everything working that I need. It's a case of sticking it all together to see if it works. I should make an effort to document it properly. Broadly speaking I'm thinking along these lines: The requirement is to be able to use a few different programs on the Stomp in a gig situation - basically amp sims, compression, and very occasionally perhaps some chorus. I'm putting the Stomp straight into a power amp, so I'd like to be able to tweak the EQ during a gig to account for venue to venue sound differences. Ideally that would be via MIDI control of the global EQ, but alas that's not currently an option, so it's going to have to be via the amp's EQs. I'm also going to experiment with the Tilt EQ block a bit, to see if that helps with on-the-fly EQ tweaks. I think I can get everything for the "head" end on a 2U rack blanking plate, though I haven't confirmed yet. I'll probably stick in 10 rotary encoders which should give me more than enough for my needs. Nextion display for seeing the settings, and maybe for saving changes. I'll have to store all the parameters I'm changing in non-volatile memory and send them every time I change the program. I've already built a footswitch as a proof of concept to give me prog up and prog down, tuner (so I can get that off the Stomp's third foot switch) and a quick way of switching between 0 gain and +20dB on the output block so that I can get enough signal into the power amp when I'm using it. It's occurred to me that I could also put Tilt or even Bass/Mid/Treble adjustment on the footswitch too, but that might be going too far. I didn't really want a ring of MIDI cables between Stomp, "head", and footswitch so that's why I looked into the MIDI thru idea, and as with everything (thankfully!) I found someone has already done it. I'll dig out the links later and post them in this thread. My main concern at the moment is whether I run the risk of introducing noise with all this hacked together DIY microcontroller based stuff floating around! Edit: Forgot to say, the Teensy 3.3v pins seem fine with the Nextion with the quick tinker I've had. Time is the real killer with all this. Having jumped onto the Nextion learning curve I'm now on a Photoshop learning curve, trying to see whether I can get some reasonable graphics together for visual feedback for volume and tone controls, etc. I'd really like to get a 3D printer too, to make some decent enclosures for some of my projects, but apart from the cost of getting a reasonable one (I haven't got the patience to go the budget put-it-together-first route) but that's another huge learning curve.
  7. Rather than a Nano what about one of the Teensy line - even Teensy LC has twice the memory of the Nano. I’ve built a basic 4 button foot switch using a Teensy LC board which will do MIDI via 5 pin DIN connector and USB MIDI in parallel, so I can use it on either my Stomp or with AmpliTube on my Mac. I’ve now gone a step further and used a Raspberry Pi to give me USB MIDI thru so I can use USB on the Stomp instead. Target is to build a second MIDI controller to give me the amp EQ and volume controls in a controller on top of my amp so I can tweak easily during a gig.
  8. 5 piece pub band playing 60s and 70s soul, r&b and a bit of garage. £200 to £250 per gig in South Wales for the last couple of years.
  9. I use the Dunlop metal ones, having found that the Schaller ones had enough friction between the two parts that the strap button screw started loosening. A word of caution if you use the rubber washers or the rotating plastic thingys - watch out if you have an instrument with a delicate finish. I used these on a Tokai 335 copy, with a leather strap, and it pushed the strap quite hard against the guitar. I now have a load of scratches where the strap has rotated around the button a bit. Fortunately it's the neck strap button which is on the rear of the guitar so it doesn't show, but annoying nonetheless.
  10. A few years ago I built this - effectively a Fender Champ clone but with s solid state rather than valve rectifier: http://www.ampmaker.com/store/WF-55-4w-tweed-style-amp.html. However it seems that AmpMaker aren't currently taking orders (check the site for the reason - I daren't mention the word here!), so I'm not sure whether this will be an option within the next few months. I spent quite a lot of time looking around for a suitable kit and at the time, for UK based suppliers at least, couldn't find very much at all other than AmpMaker. There's quite a lot of stuff available from the US as I recall, and I also looked at a far east company called Ceriatone who had a pretty comprehensive range. From a quick search it does look like there might be more options in the UK now, though. (Edit - just spotted that you're in Germany, so these comments probably aren't relevant!) I found the instructions very comprehensive. I spent a lot of time reading through them before I even bought the kit, and followed them to the letter. I have a healthy appreciation of the dangers of 230v AC, but if you heed the warnings, follow the instructions carefully, and do absolutely all the checks, then you should be able to build safely. I built the amp over a few days in the Christmas holiday period, maybe spending a couple of hours a day on it. The one small thing I did over and above the instructions when I was testing was to use a second multimeter constantly attached to the power supply capacitors so that I could always see whether they held any charge or not. The one I built was a turret board construction, and came with a pre-drilled chassis. To answer the question "will it last", then I'd say absolutely yes, as long as you build it carefully in the first place. A final comment on safety. You absolutely can't take any chances. If you have even the slightest doubt about understanding the schematic (I don't mean how the amp works, but how to wire it up according to the schematic and instructions), or having the relevant practical skills to construct the circuit board, mount it and the other components, wire it all up correctly, and carry out all the tests, then you probably shouldn't embark on the project.
  11. QLC is doing the sequencing - the arduino is just triggering either sequences or scenes via MIDI, and doing tap tempo via MIDI. For someone who hadn't even heard of DMX before I found QLC fairly easy to get to grips with for basic stuff. To be honest I've only used this a couple of times this year. Quite a lot of pubs have their own lights, and it's just another thing to set up and pack away afterwards, plus I'm already doing most of the work with the PA (we're long overdue a chat to address the fact that some of the band are a bit shy when it comes to helping with setting up anything other than their own gear). Having said that, even with four RGB lights I think we can create a much better (and infinitely more subtle) effect than with the standard pub fayre of random over the top patterns changing every second. I saw that they were resistive touch so have an idea what to expect. I'm planning to use rotary encoders for setting values, so it's probably only on/off switches and navigation buttons I'd use touch for. Any suggestions for good resources for getting started with configuring the device?
  12. I’d not come across Nextion before, but I’ve done some reading and ordered a 3.2 inch version to have a play with over Christmas, hopefully. I also have a MIDI controller for the HX Stomp in mind, but for controlling EQ during a gig so that I don’t have to bend down and start messing around with the controls on the stomp itself. It’s a pity the global EQ isn’t controllable via MIDI.
  13. 32?! I have enough trouble with 8... Raspberry Pi running QLC+, Teensy board for the footswitches and code to send MIDI over USB to QLC. Only running 4 RGB lights from it, with a few sets of fades and chases set up in QLC, either free running with tap tempo, or set to change when hitting the tap button. What I really need now is a 3D printer to make some decent cases, but the learning curve has put me off so far.
  14. We're strictly a pub band, running vocals and keys through PA tops at the moment, and I get the impression that's a bit removed from the stuff you do! I'd be keen to add a sub and put everything through PA, and get some or all of us on IEMs, but I'm pretty sure I'll have a job persuading all the band. Drummer is strictly old school and won't entertain an e-kit, plus he's a heavy hitter (let's not go down the "get a new drummer" rabbit hole, though - despite being strangers when we got together a few years ago we're friends now, doing this a couple of times a month for fun, so it's not an option). Not sure what options we'd have for some of us going IEM if we didn't want to mic up the drums. On the one hand I don't know if we'd hear enough of the drums with IEMs in, but on the other I'd be worried about IEMs not attenuating the drums enough to protect our hearing. Due to the small spaces in which we usually set up I'm using ACS moulded plugs with the 27dB filters at the moment - I found things were feeling a bit too loud by the end some gigs with just the 17s.
  15. Question to @funky8884 and @AxelF - are your drummers using e-drums? If not then do you mic up the drums to put them through PA and/or IEMs?
