These arrived today. Would start building one but it is 40 degrees C outside, meaning 45+ in the shed. At least they fit on the case nicely.
A lot of these circuits are based on previous NLC modules; VCO is from the 4U VCO panel but trimmed down a lot (core is from the EN Mikulic design), it retains the sawtooth processora nd PWM. VCF is the Serious Filter (ARP4023), VCAs are from the Matrix Mixer, EGs are from the Triad, LFOs are from the dual LFO with Difference Rectifier, Sequencer is an 8 stage version of the 4Seq, Mixer is same as the Mixer/headphone amp, the Envelope Follower is based on the Buchla music Easel design with a gain pot rather than a hi/lo switch.
