Question on the MF 107 Oscillator CV Out

I have a question about the MF 107. If I use a monophonic audio input source (bass guitar) and use the 107 with the Sync in the "On" position, will the Oscillator CV Out track the pitch of the input signal? I am looking for something that ouputs pitch to CV so that I can use my bass guitar to trigger and "Play" older analog synthesizers. Will the MF-107 work for this function? I was not considering a MF-107 as my next purchase, as I was leaning towards the MF-102, but if the 107 can act as a Pitch to CV converter than I will be getting a 107 very soon!

If this will not work, what are my other options for pitch to cv?

Hi Henfield.
No, the MF107 is NOT a pitch to CV converter. The OSC CV OUT is just the oscillator at the pitch set by the front panel knob. You will need a separate pitch to cv converter to drive the Freqbox, and it works and sounds fantastic.

I also use a bass for pitch to voltage, and it can be troublesome on the lower notes, but you can get great results if you take the time to learn the idiosyncrasies of your setup

Pitch to voltage options: (you can do a search and find lots of previous postings)
- Roland SPV355 pitch to voltage synthesizer. Fun with a bass, low notes don't always track predictably
- Gentle Electric 101 - great box, can be complex to set up
- Fairlight Voicetracker - lots of CV outputs, including timbre!
- Korg MS20 plus MS02 interface, MS03
- One or more of the new modular synthesizer places have p to cv modules
- maybe the Arp Avatar, but I haven't gotten around to testing it

i would think the mf107 is a pitch>cv-converter, but i guess not then.

Remember, no pitch voltage is generated on the 107. Its oscillator hard syncs to the incoming audio when that function is enabled.
