dsp-Gplug MK-II

The dsp-Gplug MK-II will run on the SSOP-16 chip.
Measuring 5mm x 6mm, this chip is even smaller than the dsp-G1 8-pin DIP chip.

The chip makes it the smallest stereo VA-synth in the world for sure!

The MK-II will also be available as a standalone SOIC-20 chip for those you that feel comfortable soldering SMT.

    Hi! Great project – will the mkII have the same topology as the mkI?

    • janostman Says:

      Yes, the MK-II chip has the same base MIDI-CC’s as the MK-I chip.

      But it’s stereo output, has a stereo chorus/flanger unit that have additional MIDI-CC’s,

      And some other goodies 🙂

    Please make the CC #’s reassignable on this revision if possible!!! PLEASE!!!

  3. janostman Says:

    That would require SYSEX for the mapping but I’ll see what I can do.

  4. janostman Says:

    I’m also looking at making it modular like the Nord modular and that would also require SYSEX for the patching.

    This sound very promising.
    Don’t stop us from using “audio” as modulator even if the chip doesn’t handle it well – the output from an DCO could be used as modulator for a panner or of course to modulate the cut off frequency of a filter, or blend between filter characteristics, run an LFO thru a filter etc etc.

  6. janostman Says:

    The virtual patch cables will all have the same levels and they run at sample rate so anything can modulate anything.

    You can even patch a gate signal to an audio input, even though it might not produce anything useful, it can still be done.

    A logic output flips between -32768 and 32767 and a logic input checks if the input is higher or lower than 0 so routing audio to it might produce some fun effects.

    Patching two outputs to a single input will simply add those two outputs without any level checking so it may overflow.

    But I wont put any constraints on the patching so it can be patched in anyway possible.
