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 love the sound of the mks30. Is it normal for the chorus to cause more noise? I hear noise in sine wave fashion going from left to right. Of course you don't really hear it when playing, but it's there

To chris poacher: Chris if your MKS30 is noisy then it has a fault. Most likely it's the coating on the A1QH800170 VCF IC's. You can find the solution on youtube. But dont do it yourself if you dont have the needed skills.

just fixed the 80017A chips with the acetone dip! noise went away and sounds excellent but now i have another issue? after it warms up for about thirsty minutes the panel switches stop responding? I can change them using Program change on my DAW and MIDI? any ideas what could be the problem and why the front panel switches stop responding? HELP!!!!!

One of my mks-30 chips must have started to get the crackling problem recently so i had all the chips cleaned (coating took off) and sockets put in to replace them easier with clones if i get any problems later on
it all sound great now how it did before apart from one of the voices is slightly quieter than the rest, i can see which one it is by doing the test mode (midi & dynamics button)
it doesnt sound bad or crackling just slightly quiter, any ideas? Is there anything to adjust it inside?

p.s. I also found that on the 3P the programmer is not really an issue, with the MKS it's a must as the up and down increment values are too slow to do filter sweeps etc, whereas the JP you can use the data slider to change cutoff freq very easily.
