stimresp in Uncategorised | 04/03/2012 New Baby: PreenFM I built my first synthesizer today. Yay! Constructed from the PreenFM kit, it’s a 6-OP, 4 voice FM module with 2 step sequencers and a 12 slot mod matrix. Need to re-solder some joints but she’s alive. Alive I tells ya! 🙂 Here is the First Note.
