Roland MKS-30 PLANET S

Roland MKS-30 Image

The MKS-30 is a MIDI rack module version of the JX-3P with some enhancements. It is an analog synth with two DCO's (digitally controlled oscillators) per voice, six voice polyphony, it responds to velocity, and has 64 internal and 64 cartridge memory patches. The typical assortment of analog filter, envelope, LFO and oscillator sections are here with easy and straight-forward programming. It can be controlled by the PG-200 programmer for easier hands-on tweaking. Never quite gaining as much popularity as the JUNO series synths, this synth is as good as inexpensive analog gets! It is used by Cirrus.

I have to reluctantly agree that the JX-3P sounds better than the MKS-30, I've owned both and eventually sold the JX-3P due to lack of studio space and regretted it. I did have time to do some A-B comparisons before I sold it. Yes the MKS-30 sounds very similar but the output is quieter and has far more background noise than the 3P ever did [and yes the output switch is set to H].

Just need to comment that someone said that the JX3p sounds better than the MKS-30. Are you joking? Or do you have cloth in your ears?

I dont know why people think the MKS-30 is a JX3p. It's a GR-700 in rack. They did not use the JX3p as basis for the enhanced rack version due to all kinds of horrible design mistakes in the JX3p. Thus the MKS-30 is a completly different synth (read 'better' synth).

After i got the voice chiped pelted out, I just confessed the actual MKS 30. Way far nastier than Jx3P. Totally different kind of catagories. However im facing new problem, the power just went off , can u help me to fix this. I'm sure it must be sumthin' wrong with the transformer or PSU area but I don't know exactly where, cuz I don't have a basic knowledge of electricity.
