I've had an idea for making drones when playing keyboard. I think I'm gonna buy a couple of capos, the kind that clip straight on without any adjustment like this...
...and then use them to clamp down certain keys on my keyboard. I've tried lodging a plectrum between the keys, and it works pretty well, but the plectrum does slip out occasionally. Capos would probably be a more costly solution, but I'm thinking they'll probably do a better job.
Surely this must have been done before? Somebody please tell me why it's a bad idea.
I've been experimenting with plectrums and tape already. Literally 'clamping' the keys down with a capo seemed like a more reliable solution. Anyway, I bought one today and it didn't work out how I expected. So there's a tenner down the drain, ha... Sticking with tape for the time being, I reckon. A debit card works pretty well too, but that definitely isn't very sensible. My keyboard definitely doesn't have a hold function. It's a Yamaha PSR-210 which I picked up for £10 at Cash Converters.
The best solution I can think of as a fellow charity shop keyboard owner involves the head of a toffee hammer (or something similarly compact and heavy) and some blu-tac. I understand what you're trying to do here, but I got around it by overdubbing and trying not to think about how I'd recreate it live with only one pair of hands. I'd probably use an EXH Freeze, if it came to it.
Are you just droning a keyboard to play guitar over? Or droning it for more keys over it? If it's the former, either get a keyboard with a latch or hold mode, or use a latching footswitch in place of a sustain pedal.
If you need more keys over your droned notes, the ehx freeze works great.
