Hi to all the u-headz...

I made some patches the last days using the mapper acting as a step sequencer for pitch control and i just would like to ask a question: is there a way to make the mapper retriggering notes like a real step sequencer?
I would like to be able to do one note triggering sequences the way zebra's arp do.
Is there a tip for using the mapper as a key retrigger in ace?
Thanks a lot.

Vinz

Hmmm... not exactly, as that's not what the mapper is meant for.

You can nevertheless use it as a waveform in LFO2 ("tap map"). If you combine that with e.g. a rhythmical pattern in the Ramp Generator (see manual on how to sync it and all), then you can simulate a sequencer in a way.

However, built-in sequencing or arpeggio wasn't ever the scope of ACE as "a little MS-20 like precursor of Berlin Modular".

It would be cool though if you could trigger the envelopes externally. On my SH-2 you can trigger the the envelope via the LFO for instance. It'd be really bad ass (and I've thought this since the first time I tried Bazille) if the oscillators had a dedicated pulse output (0-5v) with variable width, which could be use to trigger the envelopes. Of course this would require the envs to have trigger inputs, the oscs would require additional I/O and controls, and there is the issue about how this would effect polyphonic patches when triggering an envelope from a monophonic source...

Pay no attention to me, I'm a bad influence.

That reminds me, I had the idea it might possible to get some interesting looping envelope shapes with: ramp generator, the multipliers, and LFO1 ( not real sure how that would get wired up though

)

Maybe Zebra could be made to output midi to ACE and then you could use its arp

I'm actually thinking of it. It would merely be a selector though, not a cable.

The envelopes would receive trigger signals (not gate signals) from LFOs so that they would fall back to Attack from Decay or Sustain. This would however only work while gate is on. That is so because the polyphonic voice architecture relies on VCA envelopes to determine whether a voice is playing or not. SO, as long as a key is pressed, any envelope could be retriggered by LFOs etc.

What do you think?

Guys, maybe easier will be use external midi arpeggiator? For example ARPG8R or something like Hypercyclic.

Ok, i will try to make a "real fake" sequencer using the ramp in sync for triggering sounds on each step of the mapper...

I'd like that. That's essentially how it works with my Sh-2, which I love. You know me though, I'm gonna ask for crazy impractical stuff but I'm perfectly happy with Ace as it is.

Sure, but those don't have cables! What's the fun if there are no cables?

Ok so here i go: http://www.sendspace.com/file/woi6nj

I tried to emulate a "real fake" step sequencer and think it works (almost) fine... the thing is: there's a problem with sync on ACE!!!

Try it yourself: after a few bars, the LFO2 or the ramp generator (?) goes out of sync for a few bars and then return to sync... it's cyclic... maybe i'm wrong with the ramp settings or with the LFO2 sync settings... don't know...
or maybe it's the multiple that is used to "gate" the sound on each step...

Anyway, i'm happy to have found a way doing the trick i wanted...
the out of sync thing happens much more radicaly with my "on the run" fake and cheap cover (hey i made this in less than 15 minutes

) but that's because it's uptempo...

Urs, did i found a bug in ACE with that?

Might be the LFO... the Ramp was out of line during beta testing and should be rock solid by now.

(I'm currently smoking my brain about finding a trick to keep LFOs in Sync while allowing for rate modulation *and* swing... there's really a paradox in there...)

Thanks for the quick response Urs.
Do you think you can fix that?

Anyway, thank you so much for the joy ACE gives me everytime i play it!

Yes, I hope so. Won't be too difficult, it's just so that the LFOs in ACE are also "normal" oscillators (and vice versa) so it will be relatively difficult. In comparison, the LFOs in my other softs are all just that, LFOs.

Yeah

Thanks Urs, looking forward for that fix!!!
