"The modification that was done gives control voltage inputs for
1. Slide
2. CV
3. Gate
4. VCF (filter cutoff)
It also gives an additional output of the PWM waveform.
The original CV ins and outs all work also. The new CV/Gate input is better than the original (there is a lag on all the original 202s) I think most people would prefer to use external controls as the internal sequencer requires thought and time to program. However the internal sequencer affords special results with the use of accents and slides.

While the MC-202 is often compared to the TB-303, I think the sound and filters are closer to the SH-101. When the resonance is set very high the machine becomes very acid. It synchonized via din sync.

There are two wave forms Square (with PWM) and Saw. There is also a square Sub Oscillator that can be shifted one octave down, two octaves down, or down two octaves with PWM.

The MC-202 is obviously a great bass line synthesizer. The Sub can be absolutely devastating. "Watch the bass bins...." The MC-202 also excels in making acid. The combination of solid bass, acid sequencing, and filters that take on a life of their own when you krank the resonance, makes for acid bass lines or great sqeeky acid effects. The MC-202 also makes very nice strings sounds and woodwind sounds."

"Elektron laser-etched numbers into the last 200 Sid Stations that they made. This one is laser etched with the number 14. So, it was the 14th to last one ever made!"

Or is it the 187th to the last made?

"Korg Analog Sequencer, the SQ-10 Model. It is in fully working condition. This old school sequencer was designed for the MS series, using CV/Gate Controll. You can make some reall groovy basslines like the TB-303. It has three rows of 12 steps for a total of 24 or multi timberal 3 seperate channels (3 channels of CV control), 1 Pattern, 1 Song, 36 Knobs in all. Cosmetically, I would rate it at 8 out of 10, it has minor scratches, blemishes, which is typical for an instrument that was produced in 1978."
