"Fully functional (serviced recently) and cosmetically in very good condition bar some scratches on the top, all the pots and switches feel fantastic. This Lambda has been modified, these modifications substantially improve the depth to programming the lambda and greatly increases the range of sounds you can get out of it, here is a list of all the mods:
- Individual volume control for each preset (the knob under each switch)
- "Tone" controls (terrible 1 pole RC LPF) have been replaced with a resonant AS3350 lowpass & bandpass filter with cutoff and resonance pots (the switch at the end of the row of knobs changes between them)
This new filter sounds really, really fantastic.
- Both the sections (percussion & ensemble) go through the new filter and into the ensemble, as the fake "stereo" on this synth is the percussion through the left and ensemble through the right, this makes the synth mono, and they only go through the ensemble chorus channel (percussion chorus button does nothing).
- Percussion level slider is now dry/wet mix for the chorus, ensemble level slider is master volume.
- L & R Output jacks are now Chorus External input jacks
- Headphone jack is now filter cutoff CV input
- The trigger out has been changed to a positive gate signal (0V normal and goes high when pressing a key, normally it is inverse to this and incompatible with most things as a result)"

"I bought this new in 1996. It has almost never been used. Everything works. However, I have not done any O.S. upgrades on this unit, and I'm pretty sure it could use one. The current O.S. is 3.00. For me, the coolest things about this synth is the arpeggiator (it does arpeggios that I have never seen on any other synth), the real-time knobs (very analog-like control), and the awesome keyboard which is (as far as I remember) the same as the one used in the Roland A-70 controller, which is semi-weighted and feels amazing. The black keys have an almost wood-like feel."

I does give you a sense of the tonal capabilities of the CS70m.
