hey guys, sorry to dig up an old post...
fantastic work on this looper! i love the sound of the 'lo-fi junky', which i think this would be similar to.
but for MY tastes... a looper isn't really a looper unless you can overdub.
i know this chip can't do overdubbing, but i was wondering if it would be possible with two chips?
now i'm a total noob, and i'm sure this might have alot of problems associated with it...
but here's how i see it:
you have two isd1xxx chips: A and B
1. initial loop gets recorded in chip A, playback starts from chip A after memory is exhausted or person ends loop.
2. Overdub mode would consist of chip A's playback mixed with the live signal, and recorded in chip B.
3. The next overdub layer would be chip B's playback mixed with the live signal and recorded in chip A, and so on.
this would even allow for one level of "Undo" since you could toggle back to the previous chip if needed.
of course the sound is gonna get really muddy really fast, do to making so many analog copies... but it might be cool.
just curious to see what y'all thought of this... again great work on this one!
