"The Moog Memorymoog Model 345A is an early-production version of Moog’s flagship six-voice, three-oscillator-per-voice analog polysynth from the early 1980s. It delivers the same massive, layered sound the Memorymoog is known for, combining classic Moog filters with extensive modulation. The 345A designation mainly reflects internal production labeling rather than a feature difference. Today, it’s regarded as one of the most powerful and collectible analog polysynths ever built. This one was just serviced by our in-house technician...
Service notes:
-Installed kenton midi retrofit kit
-Modified bottom panel and keybed frame as per instructions
-Fitted midi jacks and push button switch to reaer panel
-Recalibrated entire unit and bench tested for several hours"

"The Jupiter 6 is a fantastic analog polysynth that's a little bit of an underdog compared to its siblings the 4 and the 8! However, it is very powerful and is likely overlooked due to the immense fame of the others. Its a dual VCO 6 voice with cross mod capabilities, sync, and triangle, square and saw waveforms. The filter section includes standard low pass but also band pass and high pass operation.
The filter envelope routing is not preset so envelope 1, 2, or both can be assigned to control the it! The LFO section is fully featured including a random output and onset delay. Of course there is full preset saving and plenty of performance oriented controls. The one downside is that it does not include chorus or ensemble like many of the other Roland polys! It does have the coolest color scheme and those futuristic aluminum sides though. The external analog ins include arpeggiator clock in, patch shift, pedal hold and CV for the VCA and VCF. Of course it has MIDI as well so there is tons of interfacing available.
This synth is in excellent working condition and was recently serviced by our in-house technician. It arrived at our shop in need of a little TLC, and it has since received several replacement potentiometers and sliders. A few knob caps are mismatched in color, but these cosmetic quirks have no impact on its performance. Everything has been fully tested and is functioning perfectly.

Donner L1 // Four evocative patches [no talking, audio only]
video upload by Dexba
The Roland SH-101, here reimagined by Donner in the L1, didn't offer most of the amenities we are accustomed to today, but I wanted to try to come up with four patches that could show some other sides of the instrument, closer to my likings. I hope you will find them of some inspiration 🧡"
