apart from I have this all, Id quite like this , but I have my doubts:
The strength of the Organelle is not only its a complete hardware solution, but also because the software specifically supports it… and that allows the community to develop specifically for it.
but there are still challenges
- its perceived as ‘expensive’
now consider that for a second… a rPI + piSound, , with the extras you mention (plus some development costs), that’s going to be at least the same ($450+) … look at the GR-1, that’s was 850 euro!
for the record, i actually don’t think Organelle is expensive, once you consider development costs/small market, cost of holding stock… something many people don’t seem to appreciate.
- its not an OP-1,
when you have a more complete solution, users start getting ‘lazy’, even if they know its a diy platform, they want it work out of the box, and the expectations grow with the more you provide.
but when its open source and flexible to ‘do anything’, where does this stop?
or how do you pay for continued development (which is often an expectation)… paid upgrades?
one final thing… the ‘custom controller’ aspect is perhaps tricker than you might expect. I know Johannes from Axoloti has gone thru many iterations for the upcoming Axoloti Control, its a pretty big design task, which when faced with a flexible platform … has to compromise…
how many knobs? how many encoders? how many buttons? size of display? you will get as many opinions on these questions, as people you ask.
all that said, i think using the rPI as the heart for a dedicated synth is a good idea.
I think tasty chips with the GR-1 (granular synth) have shown how it can be done brilliantly… (well when they deliver it will be), just a pity its not open source, but perhaps understandable to allow them to recoup their investment.
