Octatrack + Pulsar23 midi issue

Have had both for a while, but have always sequenced the pulsar with my pc, and everything worked fine.

I started sequencing the pulsar with the Octatrack, and all was well until I started sending MIDI clock from the Octatrack midi out, at which point the pulsar’s notes got stuck and wouldn’t receive further note messages, but is clearly receiving clock.

I have tried toggling all settings in the OT Sync settings menu, nothing has any effect except for setting midi clock to “recieve” or none. OT is receiving clock from the PC, but disabling this doesn’t help.

Any ideas what to try?

Hi, :wave:

When you want to send midi on the OT, you have to pick a channel for it. And the OT is, at least to me, a bit dumb on that point. You have to click the encoder to select the channel in the appropriate track.

So you have to :

  • Go to the midi menu
  • select yout track
  • go to the src page
  • turn the A encoder to change midi channel
  • and click it

Or your pulsar might have some issues getting clock + notes messages but idk anything about the pulsar so…

And I wonder which port are you using to send midi from your OT to your pulsar ?

MIDI Out will let the note messages get from your OT to your Pulsar while MIDI Thru wont, i believe. It’ll only send clock or any messages that the OT isn’t configured to read.

So let’s be clear: here is your setup, right?

Computer → (midi in) OT (midi out) → P23

In such configuration, computer’s messages are not forwarded to Pulsar.
You this need to activate both sync receive and send for Pulsar to get the clock.
Same with transport for it to get sequencer start/pause/stop.
If you setup a correct midi channel on a midi track, like @_opal said, you’ll be able to send notes and CCs messages, if Pulsar can take it.

If you use midi thru, computer’s messages are forwarded, but OT messages are not transmitted, so you can’t send notes from OT.

What are you trying to achieve exactly?

The point was to sequence the pulsar with the OT, which is synced to the DAW. And yes, the midi messages are forwarded from the DAW to the pulsar, for some odd reason.

I solved the issue. My setup was pc midi out to OT midi in, OT midi out to behringer pro 1, behringer pro 1 midi thru to pulsar.

The pro1 required a firmware update. Without it, stuck midi notes were a common issue. Now everything works fine.

Oh.
Ok.

May I suggest to look for a mioXM or something alike?
It changed my setup big time, making midi routing so much easier it let me wonder why I hadn’t got one before.

This experience is really making me consider why I haven’t done that yet. Thanks for the tip, this might be the nudge I need!

I remember I used to think I’d better get a new synth than a utility. Foolish me :sweat_smile:
Definitely not a luxury.

All one needs is jamming with a couple friends to understand how useful it is ^^
