"The Grp Synthesizer A4 is a direct descendent of the flagship A8, providing the same analog sonic power and flexibility at a fraction the price. Ideal for everything from smooth Minimoog-like leads to distorted, tearing bassline sequences, the A4 is equipped and ready.
"This was recently serviced by Belltone Synth Works just outside of Philadelphia. The sliders and pots have been cleaned, modules repaired, and it has been calibrated to Roland's specifications. This particular 100M comes with the 112, 120, 130, 140, and 150 modules as well the model 181 49 key controller.
There is the slightest dent on the top of the controller (see photos for condition). The keys are a little loud / clacky. The modular itself is in very good condition. There is some wear (once again, see photos for the condition).
I am including 5 cables to connect to modules to the cabinet-- one of which is NOT original. I am also including the longer din cable that connects the controller to the 100M as well as a handful of patch cables.
Most of these System 100Ms are 100V. This one is no exception. It would be best to use a stepdown transformer to convert US mains voltage to Japanese mains voltage.
This is a well cared for System 100M. I am selling it because I need to make space in my studio. Testing it out before listing it, I was tempted to keep it. Alas, I just need the space."
"The Moog 'Sanctuary', of which only 100 units were ever made was the brainchild of David Van Koevering. Moog Music brought Van Koevering in to guide their marketing efforts when the company had developed a stronger national presence. David worked with local church groups to find a unique marketing outlet for a custom-named set of Moog instruments (the Sanctuary and Joyful Noise designs,) re-branded versions of Moog instruments designed and programmed to appeal to more traditional church markets.
This was recently serviced (November '22) by 'SynthPro' Jareth Lackey. (invoice for works carried out included) and also now includes a modern, bespoke internal powersupply from 'Synthtaste' for added reliability.
Everything works as it should, pots and switches are all behaving perfectly.
The cabinetry is in stunning condition, it really is a synth to behold.
A short video is attached which Jareth recorded after repairs were carried out."
"Alesis A6 Andromeda Analog Synthesizer. Very powerful synth engine for sound design. Oberheim and Moog filters. Sixteen voices! Multi-timbral. This unit was serviced by an ex-Alesis technician and works perfectly. All components pass calibration. Includes Manual, original sustain pedal and a spare set of key bushings."
"A bit of random explorational play - the last thing to be uploaded that was done with the SOMA Cosmos.........putting it through its' paces................
"The Pam PRO’s expanded Euclidean section provides a highly musical tool for generating patterns in both triggers or any CV produced by an output. Helpful realtime visual display plus the additional pad and shift parameters take Euclidean sequencing further, allowing for more intentional patterns and variation. Here we take a look a few examples of how Euclidean sequencing can be used.
This is part of our new video series where we take a closer look at the more unique and powerful features of Pamela's PRO Workout. Subscribe to stay up to date on upcoming videos in the series!"

"Overview The original Roland 100M (1978) has only one type of voltage controlled filter, 24dB low pass. This rather limits the range of sounds that can be created with the synthesizer and it is strange that Roland never ported the 703 2-pole OTA SVF into the 100M format. The AM8122 closes this gap and provides two 2-pole State Variable Filters in one 16HP module.
AMSynths Design The AS3320 chip is used to create the SVF, rather than the CA3080 OTA in the original 703 module. This is partly down to the limited PCB space for two filters and partly because the 3320 chip in SVF mode sounds very good, think Oberheim OBX. An alternative approach would be to build a dual Jupiter 6 SVF with AS3109’s, but this is tricky to achieve given the limited PCB space and we already produce a Jupiter 6 module – the AM8060 module.
The AM8122 circuit reuses the 2-pole SVF in the AM8325 and adds the BP mode and voltage controlled resonance. The third CV input is used as the Resonance CV input. The front panel design follows the Behringer 121 module with signal and CV input trimmers, frequency and resonance on 30mm sliders and green and red indicator LED’s.
Each filter has two outputs, with a slide switch selecting which filter output goes to which jack socket. The upper jack socket (OUT) can be set to either LP, BP or HP and the lower jack socket (REV OUT) follows the reverse (HP, BP, LP). This approach ensure the LED’s track the filter mode selected by the switch, whilst still providing individual outputs of each filter mode. The three signal inputs of the second filter are normalised to the outputs of the first filter (HP, BP and LP), so that the filter modes can be mixed together and filtered again!
Front Panels The panels use the same manufacturing process as the earlier AMSynths 100Mmodules, with a white silk screen over a dusty grey powder coated panel.
Outcome & Availability The module and panel were designed in December 2022. In 1Q23 the prototype PCB’s were debugged, with the revised LED drive and increased filter output levels so they are all the same (10V p-t-p). Production modules will be availble in 3Q23. The AM8122 will be the first AMSynths module to use SMD manufacturing processes (JLCPCB) for the PCB’s."
