Just started experimenting with the MSEG and quite dismayed to find that the timing drifts all over the place... TBH it's not a little off it's not even close.

Any ideas anyone please ??

Also while using the MSEG, the buttons on the rest of the synth strop working correctly, the seem to resist moving from where they are and spring back when you try to change them.

Are the Attack, Loop and Release knobs of your MSEG set to 0?

Cheers

That sounds like an accidental midi learn.

OK the weird button action has gone since I reloaded the patch so it may well have been as you said, but sadly the MSEG still will not keep time. I have checked the attack and release and loop buttons and the are dead on zero or 1.0. I really think this is a bug.

Ya know I had a similar timing issue with the ARP a while back, I have a weird feeling this is a reaper issue. It may well be time to invest in a proper DAW like ableton... hmmm

In Live and Numerology (the DAWs I have at hand) the MSEGs and Arp follow tempo perfectly. I'll try it in Reaper in just a moment.

Thanks a lot friend, would really appreciate that.

Yeah, it works fine in Reaper 4.2.1 as well. The Attack, Loop and Release parameters should all be set to Zero.

well I am stumped as I checked those multiple times just to makes sure. mebbe should try to make a basic patch just to check it more thoroughly.

Thanks again

OK I think I have found something. For the original (faulty) patch I was modulating the bus 1 volume to produce some gated noise. I tried switching the MSEG to osc volume and lo and behold it keeps time. it seems that bus volume modulation is the problem

http://www.box.com/s/d919ac3b0f49cc653bde

Here's the patch, there should be 2 MSEG mods... bus volume and osc volume, try both. I found OSC works fine and BUS volume doesn't. Also, play 1 long sustained note over several bars to test.

ignore that, now the osc volume is all out of time too, I am literally tearing my hair out over this lol

Ok tested the MSEG in alchemy and it is working fine.

A tricky technical point:

The OSC volume mod is additive. It's the volume knob plus the value of the MSEG.

The bus volume mod is a multiply rather than addition. The current envelope is scaled by the mod value rather than summed with it. With a negative mod values, it's inverting the mod source rather than subtracting.

In the patch you posted with both active the end result of these modulations on top of each other is definitely a little unsettled. Things sound more in sync to me with 0 bus modulation, 0 osc volume, and MSEG1 for osc volume modulation - essentially gating.

Hope this helps

they are not supposed to be active simultaneously, they were supposed to be for comparison of modulating each individually. I've since found both go out of time anyway. I checked with my alchemy MSEG and it works fine, so I am a bit stumped ATM.

Thx a lot for taking the time to look at it
