Mystery Modular

Lester Barnes posted this on AH asking if anyone on the list knows what it is. If you do, please share. Title link takes you to more shots.



"From what I've worked out the thing has 6 VCOs with various features, 3
VCA, Noise/S+H, 3EGs with toggles for speed, 2 filters: one is Low pass or band pass with subtle cutoff slope and doesn't self oscillate with reso at max the other is a multimode but without Resonance. It also has a 3 input sum mixer, VC Reverb, VC Echo - with 3 separate echo return times and controls. VC Vowel Filter - Bloody Lovely, Equalizer, inverter Divider, Counter clock. It has a two manual keyboard each with a joystick and the cabinet has two separate keyboard control sections as well as a basic CPU ? There seems to be an input for 'GUIT' guitar ? and a din input marked 'Micro 15'

Patches are made on a 60 x 60 patch matrix and there are ten output faders as destinations on the row E - 5 for Left and 5 for Right -

The most unusual thing and the thing I haven't sussed out yet is the functions of the Sequencer: Its a 3 x 10 analogue sequencer. rows A+B are clocked together but row C can travel at any subdivision of the upper rows clock speed. As you'll see in Picture 3 on the link, at the far right of the cabinet are 4 groups of 4 controls - each group has a Left and Right control and two dials above - - in picture 4 you'll see another 10x10 patch matrix which has something to do with the 10 stages of the the sequencer and L+R outputs of each of these groups of four dial named GC,CY, CC,B and 58 - putting a patch pin into column 4 row 1 produces a beep clocked every time the sequencer passes stage 4 but altering the the voltage on that stage of the sequencer has no effect on the beep. One of the unknown controls above the L+R of GC alters the gate time of the beep - the other seems to alter the pitch - I have no idea what this is for. Row CY has a multi-step dial and toggles .. . ?"
