I nearly bought a Roland (G-33 or G-88?) bass last week, but I decided to sleep on it and then it was gone.
I've got a Bartolini multi-pole pickup and a Roland control panel to put in a Ric when I get around to doing the project.
It'll feed into a Roland GM-70 MIDI converter.
Of course, being a pitch to note converter, plus old tech, there will be some delay there.
Plus, I've no idea what I'll do with it when I have it working!
I expect I'll use my bass to trigger a Minitaur or Model D, but then I'll probably realise that I need a bass line too and my interest will wander elsewhere.
In the meanwhile, I've got a Source Audio C4, which triggers pretty well.
