=== vcp challenge #57: impromptu sequencer ===

you are challenged to make a patch in vcv rack to showcase creative use of modules, so other users may get inspired. you can also win eternal fame!

for this edition, the challenge is to make a patch with any of the sequencers from impromptu

== rules ==

  • make a patch in vcv rack using the chosen module and upload your patch to patchstorage.com and/or in your reply to this thread
  • tag your upload with vcp-57
  • you are encouraged to only use free modules in the patch (but this is not strictly required)
  • make a video showcasing your patch and upload it to youtube (if possible)
  • add a link to your video as a comment to this post (these videos will be collected in a playlist)
  • give feedback on other participants’ patches

deadline: monday end of the day, wherever you are, january 25th
(though late entries will still be added to the playlist)


Go on them I’m in on this one. So any of impromptu sequencers, there’s thousands of them, Spot the hyperbole there!?

i know, but i figured people may have a favorite or be more familiar with a certain one. choose whichever one you like, or use all of them!

Also, remember that many/most of them support the clipboard to copy paste with other sequencers, or in this case with each-other. Actually, now that I think about it, I’m not sure that’s accurate, but @marc_boule can tell us.

Definitely :slight_smile: I made a summary table near the top of my manual page for this (last line in the table):


oh, nice! Am I right in assuming that new users can start sequencing in PS16, 32, or Foundry and change their minds later any copy all their data that way?

Only one sequence at a time though, unfortunately, and things like slide and the song itself will not be copied, but with patience it can still save some time.

gateseq64 is a mainstay for me, though i tend to use it to control the structure of tracks rather than for beats. I guess this is finally the opportunity to learn Foundry that I’ve been anticipating.

Here’s one:


(I continue to like Gateseq as a drum sequencer with probability and patterns and all that, but to send control triggers - say, open a delay every 4 bars or so - JW’s fairly recent Trigs has won me over)

It’s maybe a bit weird but I don’t use it to trigger things much at all, it’s just a matter of controlling the volume of individual tracks.

I use Impromptu’s modules a lot. Here’s a little sci fi microtonal ambience for you.



I used the GateSeq with probability to trigger sample and hold notes that have some repeateing elements due to the sequential switches.

Love it. Could easily be something from Solaris (the original Tarkovsky version) or Forbidden Planet

Truly beautiful, always wondered what microtonal was, how do u achieve that in VCV Rack, visuals please! Thanks

Luscious. Spacious. Eno would have been proud to have that on Apollo.

I would be really grateful to know which video program you use to to mask out the Rack background.

you can do some nice microtonal stuff with any decent quantizer. NSYTHI’s can load scala files (and if you look online there is a whole world of them out there). And if I may be so bold, you can check out Frozen Wasteland’s Probably Not(e) series of Quantizers - the Bohlen Pierce and Arabic versions explore specific micro-tonal scales and if want to go down the rabbit hole, the Math Nerd version lets you generate all kinds of cool micro-tonal scales (all under cv control!)

Thanks, more adventures in my sound journey, I will give the Scala archive [Oct 2020] a good try out in Nysthi’s Poly Scala. Also your modules as well, I have used the Arabic version not tried Bohlen Pierce though. Much appreciated.

Thanks. Video work is mostly Photoshop, really, where I make a .png with the modules eventually cut out (and same cables redrawn) to place over the screen-recording.

I asked for a “streaming mode” a while ago so that we could just have a green background instead of the grey stuff and shadows but it hasn’t been accepted yet.
