ims20 sequencer help: how do you transpose sequences?

[schreinein]

hey all,
i've just joined this forum, so please be kind with me!

ive just bought the ims20 for my ipad2 thinking it could be handy for live work rather than trailing my real ms20, ms50 and sq10 out with me! on first impressions its great, sounds like the real thing, patches like the real thing! however, im frustrated by the sq10 sequencer! i cant seem to get it to transpose my sequences with the keyboard! when i hit play, the sequence starts, when i hit a key to change it, the drums continue, but the sequenced synth stops untill i let go of the key! yes, ive tried changing the values of the envelope gens 1 & 2, ive tried patching as i do on my real set up, like so:
sq10 multiple trig out-ms20 trig in
sq10 channel a- ms20 vco freq (2nd input on top row of patch panel)
ms20 fm's mg/ t.ext knob turned right up

no joy!

i'd greatly apreciate any help you guys could give, this is driving me nuts!

cheers,

alex

anyone? lol!

seriously, can nobody help me here? is it even possible? the patch section operates as on a real ms20, so why can i not connect the sequencer as i would on a real one, in the same way? what is the function of the multiple out on the sequencer?

someone, anyone, please help.....

I think I understand what you are trying to do, but I am having a hard time visualizing that CV patch. Can you explain in further detail how you do it in the real MS-20?

[schreinein]

hey dis chord,
on the real ms20 & sq10, the set up is as follows:
1. patch the multiple out trigger on the sq10 to the trigger in on the ms20
2. patch channel a on the sq10 to the freq. in on the ms20, set the pots to the desired value! these will give the sequence it's note value!
3. patch channel b on the sq10 to the lpf on the ms20! set the pots to the desired value! these will provide the tone colour via the low pass filter!
4. patch channel c on the sq10 to the vca on the ms20, set the pots to the desired level! this will provide the sequence with 'accents'!
5. patch trigger reset on the sq10 to whatever point in the sequence you want to loop! in this case, 8!
6. set values on the ms20 on the eg 2 section and lpf to whatever is desired! in the fm section on the pot panel, below vco mixer and beside master tune, turn all the way up 'mg/t.ext'!
7. hit run on the sequencer and the loop should start, now, whenever you press a different key on the ms20 keyboard, the sequencer should automatically transpose to that key!

i hope this helps you understand what i'm trying to do!!! i fully understand that the ims20 isn't a direct clone of both machines!! here's a link that displays the patch i'm referring to!!

Hi alex,
even if I have no iMS, MS series nor real patchable synths, I would say that you need to sum the voltages from your KB and sequencer together and apply it to the VCO to get the sequence transposed. You need to add KB voltage to the patching. Maybe you try routing Out-A to In1, the KB voltage (don't know where to get it) to In2 and from the Out (sum of both voltages) to VCO CV IN.

As said, I don't know if this are the right patching ports but I think you got the idea from what I try to explain.

EDIT: removed due double post from above!

hey axxim,
your theory is 100% right, and should work!! i've tried it, but it doesn't seem to work on the ims20! when i set up my sequence and patch, hit run, as soon as i press a key, the sequenced synth stops but the drums continue to run! as soon as i let go of the key, the sequenced synth returns!

as i said, i set up a patch identical to my real ms20/sq10 set up, it sounds perfect, however, i just cant get the sequencer to function as it would!!!

cheers for your advice,

alex

okay, the penny's just dropped!!! i created a basic sequence of 8 notes and let it run!!! i then noticed that when i changed the button of sequencer from notes to parameter, the sequence stayed the same!!! i'm wondering if this is where my answer lies?

there is keyboard cv out on the patch panel as well as trigger cv out on the ims20! any of these could be patched into in 2 on the sequencer mixer! the problem seems to be when you press a key to transpose, it interupts the synth signal and stops the synth sound whilst letting the drums/ rhythm to continue! again, perhaps the answer lies in the voltage or parameters settings?

i'm sure there's other ims20 users who'd want to know the answer to this problem! as i said, i was hoping this app would be the answer to my prayers so i'd not have to bring my real set up out with me anymore!

all the best,

alex

hey all,
sorry if it seems like i'm going on a bit, lol!!! i think i've resigned myself to thinking that the ims20 is NOT a 'performance' soft synth! it's starting to feel like it's more of a studio tool, for simple analogue style loops and sequences!! i will perservere of course and see if i can work out how to transpose sequences in real time during performances!!! if i'm successful, i'll post the patch here!! in the meantime, if anyone else can help out with this, then please let me know!!!

cheers,

alex

..... in the meantime, check out these clips i found on youtube! they give a basic idea of how to patch what i'm trying to do:

I think the problem may lay in the keyboard assignement. The KB should only be routed to the sequencer to control the pitch. If the KB is also routed to the ims20, then the ims20 may obey the KB first instead of the seq. Is it possible to deassign the KB from/to the ims20?

hey axxim,
no, i don't think it's possible to deassign the keyboard! is that not what the modular routing points are for, to connect up what we need as we need it? on the real set up, the sq10 sequencer's signals are patched into and sent through the ms20, and sent where needed (eg, pitch, filter cut off etc)!!! the ms20 isn't controlling the sequencer, if you get what i mean......

Hi. I too have a real MS20 & SQ10 and my suggestion on paper at least (as I have not tried this for years) is to use the summing amplifier as on the SQ10 - one input being the Kbd Volt out from MS20 and the other being Ch A voltage out from the SQ10 - then run the summed voltage into the MS20 VCO 1+2 in.

I have already found the iMS20 to be far from the reality of these two great real instruments on which they are based. Without full manual documentation I think most iMS20 users will end up being very frustrated.
