Totally... But they're kinda expensive to get into :( Look at the price difference between a MBHP core and the FPGASynth. Ouch. Totally disagree. This is MIDIBox :) I'm all for DIY digital synths (I'd love to render my K5K obsolete by my own hand, despite the sacrilege ;) ), and I know that audio manipulation is far more trendy than midi mangling in recent years, but MIDI still has it's place, and I think it would be a crying shame to lose the MIDI focus of a community like this :( Don;t get me wrong though - MIOS/MBHP is an awesome platform to be partnered up with an audio device, be it a SID or OPL or FPGA or...... AD switch matrix....... Yeh not to mention the SRAM extension. The vX prototype has 4Mbits of SRAM. Yes, that's an M for Mega ;D All this talk of AVR chips with more RAM than a 4620... are there any? Is it a big difference or a few K? Totally agree :) You've been reading my wiki page haven't you ;) I think I posted about this a while back too... I've got the driver basically done (it's pretty simple, it's a great chip and programming them is a snap), but the board design for the audio part is the tricky thing... IIRC (it's in the datasheet I can't be bothered reading again heh) you need to have 3 layers at least, to avoid ground noise and crosstalk problems, and if you're using it for mixing you have to think about balanced I/O too, as well as it needing 3v not 5v... I actually think it might not be that hard for someone experienced in synth diy *stares at you, moogah* ;D but I don't yet have the confidence in board design to spend the money on a prototype I designed with my n00b skillz heheheh Seen this page ? I think this kind of module would be indispensable... as well as the mixer and FX routing, and automated audio patchbays, one thing that people never mention is automated analog modular synth patching and routing... Imagine a real analog version of a nord modular... and anyone with a modular synth can hook a midibox up to it for full recall and remote editing.... droool *falls down* PS the JDM works with 4620s too
