New update pushed to Github. I glued the BEAP audio recorder onto the end of the signal path. Ended up spending the last half hour recording awesome loops.

I’d love to, but I don’t have a good workflow for doing so. It would be cell-phone shaky cam, unfortunately. When I get a chance to finalize the friction behavior, I’ll try to put something together then.

Ok, downloaded it and had a quick play. I’ve made some modifications/tweaks/additions, in a quick/hacky way.

(I wasn’t able to get my old arc to connect on my mac mini, so I’ve not tested it with the arc, or messed with any of the led stuff)

Changes:

  • Added tape saturation and compression from TPV2 modes
  • Added random dips in volume and random filtering (also from TPV2)
  • Added wow/flutter to general speed playback
  • Swapped BEAP record for plain sfrecord~ (that pop up thing was killing me!)
  • Added signal rate smoothing to all playback speed (super important, as it otherwise sounds steppy (you were smoothing with regular line 0. before instead of line~) (smoothing is from Cut Glove where the overall smoothing comes from the controller input, so the slower you move, the slower the smoothing, the faster you move, the faster the smoothing))
  • Rejigged how ‘friction’ works. Rather than it being the general smoothing, it’s instead the amount of time before the playhead comes back to rest. So kind of an inertial ‘stop’. I want to implement this better, but this kind of works how I imagined.

I was sketching some stuff the other day on how to handle the LEDs too, but haven’t figured it out quite yet (basically imitating the tape wheel cogs, and then spinning/interpolating that).

So yeah, have a tinker with this to see what you think.

Nice! I like the saturation a whole lot better than the quick-and-dirty tanh~ that I was using. A few quick thoughts…

-You’ll want to test the friction control with the Arc. The reason it was kind of hacky is that the friction is displayed on the Arc itself (i.e. you’ll see the speed control sink back to 0). I was having a difficult time coming up with a solution that kept the Arc within useful boundaries, updated smoothly, and displayed properly… This current method sounds nicer, but it’s not interacting with the Arc. The “line” method stinks, though, I agree hahah.

-When friction == 0, it should just stay at the current speed. I’ve been using this for more sustained loops and finding ideal spots to scrub. It’s also really nice when using the alternate Stretch mode.

-Wow/Flutter should have a depth control. Just a 0-1 that multiplies the W/F jitter at the last stage.

-Likewise, Random Filter/Volume/Compression should be optional.

-Which popup thing was killing you in BEAP? I typically use it with “autoname” enabled, which generates soundfiles in the arcTape directory automatically whenever you hit record. In my mind, that allowed for more rapid experimentation without breaking flow. The sfrecord~ can also give false security. If you hit “Record” without hitting “open” and naming a file first, it will silently post an error to the Max window. That’s more of a workflow thing, though. If you like to generate one big, specifically named file, sfrecord~ interferes less. If you like to generate a bunch of smaller files all at once, BEAP’s autoname is easier.

I guess, in general, I had started this as an HC-TT emulator, and then it kind of became a more general purpose arc-based soundfile manipulator as I started using it. We could do:

  1. Split this into two related projects. One could be a more dedicated HC-TT emulator, with all of the tape and friction features always-enabled.
  2. Merge the two projects, but add in switches and controls to determine exactly how tape-tastic the output is.

What OS is your Mac Mini on? There are some required methods for fixing the FTDI driver that have been posted on the updated installation instructions: http://monome.org/docs/setup/
I had to:

  1. Reinstall the FTDI driver.
  2. Restart to get the serialosc service running.

I imagine you have something specific in mind, so you can just grab whatever bits you find useful from what I put in.

I was aiming for something along the lines of scratching a tape type sound, so there was no ‘play’ really, only momentary bursts of activity, with friction being the only thing that maintained momentum as it were.

The bits I built in have parameters exposed, so it would be easy enough to make them fully controllable, or to have presets or something along those lines (the approach I’ve done in TPV2 since there are so many things to control/tweak).

The BEAP thing that was bugging me was that just opening the file would prompt me for a name, so I just pulled it out. But just a matter of preference and workflow. And yeah for creating lots of files that’s a good way to go.

For the serialosc I’m on 10.11 so I’ll try doing that. I’ve never tried my arc on this computer, but my grid does work (though it would never reconnect if I unplugged it).

My Arc returned today! I haven’t had a chance to sit down and work out merging Rodrigo’s friction changes, but I’ve added in his awesome saturation, compression, and TPV2 random macros. Compression and “Jitter” (random filtering and amplitude) are buttons, while Wow + Jitter are a smooth control. Just pushed it:

Here are my current plans for a “final” version:
-Make friction variable and better.
-Add a switch to select which control is targeted by Arc knob 4.
-Add @Rodrigo’s name to the interface if he’s cool with it.
-Cleanup the interface now that the control set is pretty much final.

Other than that, I think that his improvements have taken it to a lovely place. It’s a really fun, versatile instrument.

Ah nice, looking good!

The only suggestion I can make is to have the friction be signal rate smoothing.

And you can include my name if you want but not necessary.

So I was messing around with my OP-1 and I wondered how easy would it be to implement a “record head” in the same fashion that the play head is currently implemented - similar, to the manual record head function on the OP-1. I realize this departs from the original intent of Capstarc, just wanted to throw it in as something to think about.

I’m unable to get this thing to start playback (MacOS 10.13.2). I can wiggle the length knob and get the borders to appear, but I never actually get any sound out. Is this working for others?

Apologies for necrobumping this, but in case you never sorted this, one of the objects in the patch no longer works, at least in Max 7. If you go in and find the red/shaded out object, change grooveduck2 to groove~, leaving the rest of the arguments the same. Mostly leaving this here in case anyone else comes along in the future and has the same issue!
