Hi Tom thanks for your interesting infos! Observing the panels we notice for each memory, in addition to the activation button, 3 switches and 3 multiturn panel trimmer. I think trimmers adjust preset C.V. respectively for VCOs, VCF and VCA respectively, but there are no trimmers or adjustments for ...

Hi!
I would like to know how memory modules work on synth's patching?
Which parameters and wich modules can be controlled?
ADSRs are excluded? Do they need a manual presetting?

thanks
Alberto

Hi !
In this case the Exp position is better

Hi! This is my patching to get a delayed vibrato on a System 55 (click the following link for the picture). 921 oscillator used as LFO (triangle or sine wave abt 6.5Hz) 902 vca and 911 adsr are used to obtain the desired delay of vibrato after a key is down 995 attenuator, third in/out, adjusts the ...

Wow thanks Noddy!

MC very thanks for the full explanation, now it's all clear!

when no key is pressed all wiring/components marked in red on the schematic are unconnected, no resistor of the resistive divider closes on the pitch bar! So also with relay contact shorted, please tell me where c1 could lose its charge?! In this condition the relay appears absolutely useless to pre...

Hi !
I'd like to know the characteristics of the sample and hold module specially built by Bob Moog for Keith Emerson and also revived on the EMMS Modular System. Would welcome a picture with details of the controls on the panel
thanks

Thanks for reply! From schematic the left connection of contacts of relay is connected at Glide pot and relative on/off switch, follow the connection to the Picth busbar of keyboard. When no key pressed (or released) the Pich busbar, see schematics, appears unconnected, so also entire left part of t...

Hi ! About 951 keyboard I would like to know which is the function of the relay switch connected between the pitch bar and the capacitor C1 delegate to S&H. The discharge of the capacitor is not however possible to happen without any key pressed, infact in this condition left connection of C1 re...
