Korg ms 2000 has a motion sequencer , not exactly a step sequencer, that can modulate pitch and other parameters.

The oscar's oscs were a strange design, I would say not completely digital since they were based on 4046 phase locked loop ICs.
Thomas Henry's x-4046 vco is triangle core.

Compared to all the synths that I have used , Prophecy has the lowest output of them all.
A little gain from the mixer could help and since the overall output is not noisy , I dont see it as a problem.
Despite this fact , the prophecy is one of my favorite digital synths

It is from 125mV to 4V.

I highly doubt that the 201's filter can self oscillate but you can set both OSCs to EXT IN and have a try.
Alternatively set a sine wave to Osc1 and modulate its pitch with an LFO to reproduce the effect you are looking for.

I had no idea that beatstep pro was compatible with Hz/Volt, thanks for the info.
Did anybody try to sequence vintage yamaha CS synths ? Any issues ?

Good work Caleb!

lol!
They should have made a remake of the British awards version of 3 am Eternal, along with buckets of blood, sheep disembowelment and M16 with real bullets.

If you are going to do this then you should do it the right way. You can use common CR2032 Batteries and a battery holder, both cost less than $2. Also have in mind that lithium batteries can explode when overheated during soldering, thats why it is a good idea to use a socket. http://thumbs2.ebayst...

Hi , in the 80s/early 90s most manufacturers had the batteries soldered in the pcb, so I dont think that Kawai is to blame here. You have to lift the mainboard and unsolder the battery terminals from the pcb and then replace it with a battery holder just like the holders found in modern computer mot...

What I have noticed with my unit is that lower notes have a higher amplitude, I thought that this was Korg's trick to make it sound more "bassy". If you are talking about individual notes then it could be a calibration issue. When using both oscillators , incorrect osc pitch tracking can cause abnor...

You are probably correct about the pins.
The picture was taken from part is parts website, so I guess they had it wrong.
Part number is 362X120002, good luck finding one.

Thank you all for your replies. I use toluene (toluol). Never heard of it, I would like to try it but I cant find it in my country. In which applications is it used? Are you sure it's flux? I recently recapped a Unost'-21 where almost all PCBs were covered in what I presumed to be varnish. It looked...

I am trying to remove the old flux from CS30's pcbs , but I have no luck yet. Near all pcb's have tremendous amount of old brown flux, I havent seen anything like this before, and to prevent possible corrosion of the copper tracks, I want to take it off. So far I have tried the usual solutions, rubb...
