The classic Roland 100M VCF redesigned to use 2 x LM13700. The LM13700’s internal buffers are not used, instead FETs are used as per Roland. Project includes the addition of 12dB/oct output in addition to the stock 24dB/oct lowpass. The PCB is designed to fit nicely into your Euro system. PCBs and finished front panels are available from myself.
