So are you saying using the iPad is off the table? I read through here but I’m not entirely sure if you’re dead pan on avoiding using the iPad, or if it’s an option. I think both KQ Dixie and BramBos PhaseMaker can load DX7 sysex data (KQ definitely can, unsure about PhaseMaker).
Hardware wise, sorry, I know nothing in this area haha.
Quick edit: Also, if you’re worried about the future of the project and investing in hardware you might not use later, it might be better to just try this out with the iPad first…
For the budget, it’s hard to beat the PreenFM2. 8 voice 6op FM. Sounds great. Super small, can fit on top of whatever keyboard you use. Not the easiest to program, but by FM standards it’s really not bad. And you can usually find them for under $200.
I struggle with FM synths. Not so much the concept or programming but finding the right one.
DX7: great, the classic but too big by far
Volca FM: currently using this but limited patch memory/polyphony
Preen FM: have one, like it a lot but miss op feedback and DX7 crunch (EDIT, I have Preen FM2)
DX200: Had one previously but this was pre-Elektron gear so only used as a standalone box. Back then I knew even less than now what I was doing! Might be good to re-try
Software: don’t use it.
Much of the time I end up using FM samples in OT rather than an FM synth. Sometimes I think I should just bite the bullet and save up for an FS1R!
In keeping with the DIY punk ethic, build your own.
It’s worth mentioning that both come pre-loaded with a bank of recreated DX7 patches and there are a few user banks of patches downloadable from the forum.
Probably it should be a Digitone of any of these, but my brain might boil if I add another Elektron box to my OT and Rytm
Will be interesting to see if a desktop opsix comes out…
