MFOS SLMS – Demo
A short demo of the SLMS, showing the following features: CV input, Low Pass filter with resonance, VCA, Gate input, Attack/Release with retrig and LFO.
The CV and Gate signals are generated by MIDI interface CVpal by Mutable Instruments. The sequence is generated by Qtractor on Linux.
Recorded with my Tascam DR-08.
MFOS Weird Sound Generator in SMT
Here comes my next conversion of Ray’s classic analog synthesizer, the Weird Sound Generator!
This is the same process as for my previous SMT/Eurorack conversion of the Sound Lab Mini-Synth. The circuit is identical to the original, including component references.

MFOS Sound Lab Mini-Synth in SMT
Ray Wilson was the guy behind Music From Outer Space. He was a huge contributor to the Synth DIY scene. He designed a lot of cool projects, offered kits, schematics and a huge amount of tips and tricks for beginners. He even wrote a book on how to build an Analog Synth. MFOS kits and PCBs are still available through various resellers (see synthcube).

What’s on TV? “Everything you wanted to know about soldering and desoldering but were afraid to ask”
An excellent video on soldering techniques. SMD soldering is simple! Even if you don’t own a hot air station, the techniques demonstrated here are very helpful to anyone interested in SMD soldering.
