It’s one DSP chip, while the full size G1 is four (expandable to eight).
What this means is that it can only load one patch at a time, even though there are 99 patch memories. A patch can only ever use one full DSP chip at maximum, but the voice count can be increased for that one patch if it’s not using the whole chip. It’s really hard to explain, and took me a while to understand, and then gets even more complex when thinking about an expanded G1; the extra DSP chips are there simply for polyphony (ie. you can’t load eight maxed out patches at once, only four).
The patch I made for this video maxes out one DSP chip, so would be usable on a micro.
The micro has three assignable knobs, a note trig and a button (which I assume is the same as connecting a switch on the full size G1. It does also allow for a MIDI controller to be plugged in, and is bidirectional, so it’d work nicely with a BCR2000 or similar.
To be honest, I kinda want one simply so I can work on patches on the couch without having to drag my G1 all the way to the loungeroom That said though, maybe I could figure out some kind of remote desktop arrangement to control one of my old PC or Mac laptops…
