modular bleeps

I found this recording not long ago ,it is recorded in 2012 - November or so , and it's only survived recording from my first modular synth ,it was mostly done on stripboards ,while the panels were found materials and even cardboard, i reused pots from an old mixer for this synth a lot ,they have proven to be very good quality , one of the panels for artwork has the record sleeve of a rolling stones album
