Triggering slices with midi notes?

Yes. It would totally complete the OT in my opinion.

Come on !!! :sleepy:

it can be done if you have a device capable of sending two midi commands simultaneously ! - search here for the very recent thread - covered earlier in this thread too

You guys should really look at getting. Midipal - they’re S cheap as shit and boy are they useful.

Does anybody of you know the code to set this up in MidiBridge?

http://www.audeonic.com/mb_sbyter.shtml

Say we would like to use channel 16 to trigger slices on the active track, say, channel 11. MidiBridge then has to do the following things:

  1. Clone note events on channel 16 to CC slice number (I fear that 64 lines are needed for 64 slices, but it should be worth the effort
  2. Then, fix all note events on channel 16 to note C3
  3. Finally, change the channel of all events on ch 16 to 11 (X15=X10)

What’s the code to do that? :slight_smile:

In my opinion, playing slices and slots via MIDI is the one and only feature that the OT is really lacking! Even the A4 can do that. Did they forget the OT? Anyways, a workaround with an iPhone plugged in between is better than nothing.

EDIT: can slots be selected via MIDI (i.e., scroll through the sample list)?

I’ve followed the posts (thanks to you guys for the pointers) using Max for Live and it is working.

A lighter version (without Ableton/Max) should be doable as well. As long as a delay is inserted between setting the slice CC and playing the chromatic note, this seems to work fine (~20ms).

Here’s the Max device for Ableton 9:

(v0.2 interface change and overhaul)

INSTRUCTIONS:

IN ABLETON:
Drop this onto a MIDI track in Ableton.
Make the IO (ins/outs) visible on the mixer.
Select your MIDI controller as the Ableton track’s In.
Set the MIDI out to wherever the OT is plugged in.
Set the track’s MIDI out channel to your OT auto channel.
Highlight Monitor “In”
Highlight the Track Activator

ON OCTATRACK:

Turn on “Audio CC” under project>MIDI>control.
Select an OT track with a sliced and linear locked sample on it.
You can be in play, stopped, paused, grid, or live record mode, and any trigger mode.

USAGE:

On your MIDI controller note 36 should play slice 1 of the active track.
Change it with the “Basenote” parameter. Slices are now on consecutive notes.

Slicemode can be deactivated to use regular OT MIDI.

Increase the “Delay” parameter if notes ever play the wrong slices.

Please Elektron, implement a better way to do this!

I’m currently using the MIDI Designer iPad app to try to get this to work. Very close - sending both the note on and CC messages fine - but I’m having trouble getting them to send in the right order. Supposedly I have it set up right in MIDI Designer and the CC message is sending first, but the Octatrack is responding as if the note on is coming first. Very frustrating…I’ll try again tomorrow to try to work this out.

If anyone has any iPad solutions to getting a 8x8 grid triggering slices, let me know!

Hi All,

I haven’t looked too carefully, but this is possible with the OT Lemur template. I’ve used it to trigger slices. It’s not the ideal interface at all, but it proves that remote control of slices is possible via some kind of programming. It wouldn’t be too hard to reverse engineer from the template.

Could you pls post a link to the template you’re referring to? Thx!

Yes, this is what I’ve found too. That is the reason for the delay parameter in richiegusto’s Ableton solution at the end of the previous page.

The OT will not properly trigger the slice without sufficient lag between the CC command and the note. If you try to do it instantaneously, sometimes the slice will change from its previous value but it almost never hits the right slice for me, as though there’s a “glide” between the slices.

And I don’t know about you guys but I absolutely loathe this amount of latency. Especially when it comes to drums, which is what I’m doing a good 85% of the time when you work with slices/chains in this manner.

Interestingly, you can lock/modulate the start parameter to your heart’s content, at 2x speed at 300 BPM if you please, without this odd behavior. There seems to be something funky about the way the OT responds to MIDI messages, or maybe just this one in particular.

interesting… that seems a lot more responsive… 20 vs 60 ms, i should try it out in lemur to compare - i’m also wondering whether other cc control is this delayed, as it may not be so evident

I’ve been experimenting with other CCs lately and this problem doesn’t seem to affect any I’ve worked with so far. There’s something different about slices. My guess is that this relates to the caveat mentioned in the manual that LFOs don’t work with start time when using static samples. There may be something in the slice handling code that throttles start point modulation (for both flex & static) in an attempt to prevent the CF reader from changing addresses too fast for static tracks.

Thanks avantronica, good to know that someone else has run into the same issue.

And license, interesting idea, but it doesn’t seem to be that the OT is throttling start point modulation. You can modulate start point as fast as you want even with static tracks, and you’ll just get glitchy playback. On a flex track, you can trigger all slices immediately if you play them with the OT’s keys. The problem seems to only occur with incoming MIDI messages.

Yes, this is all true. I didn’t explain that well. I mean that it seems to throttle the start point control from CC 17, like there’s a slew limiting on just that particular controller. Static tracks not being able to read from the card fast enough for proper start point modulation is the only purpose I could think of for this behavior.

interesting because i was sure i had managed to trigger slices with that template…but when i tried again, all i could do was select them. i strapped a midi monitor across the output and there was no trigger note going out, only the cc17 for selection.

are you absolutely sure you were able to trigger them rather than just have the OT sequencer triggering the slice you were selecting ?

I just got a response to my support request about the slicing problem. Here’s what Elektron said:

The CC messages and the Midi Note messages are processed by different parts of the system where the MIDI Note has a priority. The best solution would
be to be able to trigger the Slices directly from MIDI Notes since there
can be a difference in delay of the system handling CC depending on the
load of the machine. I have forwarded this request to the developers but I
can not promise anything.

So they’re aware of the issue, but no promises about a solution. It’s a pretty significant issue for a slicing sampler, and it seems to be feasible to fix it, so I have some hope…maybe if some of you chime in to support they’ll recognize the desire for this.

What no one seems to have talked about is that slices require a single value: only one slice can be played at a time per track. So why would you transfer the current , well-adapted “monophonic” slice CC system to midi notes, which are set up for polyphonic applications? :confused:
Also, imagine you have your slices laid out on pads, what happens if you hit 2 pads simultaneously? If 4 or 12? Which slice gets played? Will the octatrack crash, or just play the last value?
Go on and convince me that this would not be a problem…

Not sure what you’re getting at here. The problem is that you can’t trigger slices consistently from an external controller because of the way the OT processes CC messages.

No one is suggesting that the Octatrack can/should play polyphonically. Using MIDI notes doesn’t imply polyphony; you can trigger a monosynth with a polyphonic keyboard just fine.

And finally, there’s is no way to play 2 pads simultaneously via MIDI, as it transmits messages serially. There’s always a last note to play, and that’s what the Octatrack will play when triggered. No worries about crashing.
