Sequencers with multiple MIDI outs in Cubase 9

[ChamomileShark]

hi, I have several Reaktor based sequencers which output different sequences from a single ensemble.

I'm trying to figure out how to have different sequences routed to different instrument tracks.

I've set up one instrument track set to receive MIDI channel 1 from sequencer 1, another to receive MIDI channel 2 from sequencer 2.

However when I hit record in Cubase 9 on both tracks they are summing, ie it records the MIDI data sent from Sequencer 1 & 2 on both tracks.

I'm pretty sure the sending from Reaktor is right as if I use Kontakt, set it to receive on ANY channel in Cubase and then within Kontakt individual instruments set to recieve 1 or 2, I'm getting two distinct sequencer lines.

Any ideas?

Your last sentence is .
You want the MIDI input on/for the track(s) to be specific. If you were sending, eg., to a multi in Kontakt, the 'global' MIDI channel is 'omni/all', yes, and the individ. .nkis will be specific channels matching Cubase Inspector. But your statement appears to have Cubase tracks receiving Omni which would give the result you're seeing.

[ChamomileShark]

ok, if that's the issue how do I change it - how do I stop the two instrument tracks receiving in omni mode? The term "omni" does not appear in the manual.

If you mean "any" - I thought setting the instrument tracks to channel 1 and channel 2 respectively did that?

[Googly Smythe]

Caveat: I don't own Reaktor, just using what I remember of hardware behaviour.
Wouldn't you need to set the output channels of Reaktor to channels 1 and 2? If they're transmitting on the same channel Cubase will record both on whatever tracks are recording.

[SJ_Digriz]

If your Reaktor ensemble is showing as a MIDI input on the MIDI dropdown list for the instrument tracks, you can use the inputfilter to restrict which channel is passed through. Then you would have to figure out how to set the output channel from the Reaktor sequencer.

[jancivil]

Well, the Input Transformer shouldn't be necessary unless the instrument supposed to receive the MIDI cannot parse channel. I'm kind of buffaloed here.

I'm sorry, I wasn't quite awake when I replied. Reaktor is only going to be 'Reaktor out' for your other Inst. Track's input, isn't it. I'm an idiot. It is omni (ie., all) per se.

So the thing that separates them is down to your Reaktor ensemble, I think. I'll assume that you have set up the ensemble to send MIDI channel from Instruments below the ensemble and one of them is ch. 1 and the other ch. 2.

You have Reaktor instantiated as Instrument Track and the other Instrument Track shows as input 'Reaktor out', yeah?
Sorry if this is all too Captain Obvious but I'm trying to be absolutely clear what we're looking at, on the same page. Then you have two instruments in a Multi in a multitimbral vi or two discrete instruments and ch. 1 should receive ch. 1 from Reaktor out as MIDI in and ch. 2 should receive ch. 2 likewise.

Ok. Rather than try to assume and deal in abstractions, I want to see it. I don't have handy a Reaktor Ensemble with more than one sequencer to look at. What I'm looking at is:

So the Ensemble has no way of setting more than one MIDI channel. What does yours look like?

What's the name of this ens?

[ChamomileShark]

hi, these are ones I built myself.

One is based on the basic (Bento?) sequencer. I've then copied that several times and added one of the MIDI out blocks.

Those MIDI out blocks are then set to different MIDI channels.

When I go into the side panel for the block set for Channel i it looks like the image above. The one for channel two has "2" in the MIDI out.

You are right in that the only in for the instruments is "Reaktor out"

But as said, if I then take this ensemble and pair it with Kontakt 5 then it will allow me to have one instrument say cello playing on one MIDI channel and another say Glock on the other - so I'm getting my two different sequences.

This is an image of the block I used - apart from making sure I had one showing channel 1 and the other 2 within the GUI I also checked in the side panel for the two blocks.

So in Cubase if you want an instrument track or MIDI track to only respond to one MIDI channel, you use the tracks input transformer option. So you can have the Reaktor instance be the MIDI input for any track, then use the input transformer on each track to restrict what it listens to. There are presets there for channel masking.

ok, this is looking promising but so far it's not working. This what I did

on my instrument track 1
open the Inspector,
click Input Transformer,
select "Local" from the pop-up menu.
took the preset Channel filtering - pass channel 1

did the same for instrument track 2 - but set the local transformer to pass channel 2

I'm still hearing both instruments responding to both MIDI channels

On the bottom of the transformer window there is a "transform/Filter" option dropdown. You probably had it set to transform when you loaded the preset. Set it to Filter

Unless you have Cubase Elements you can use midi monitor plugin to see what arrives on various tracks and channels etc.

Really useful to troubleshoot these kind of things.

And sometimes there are discrepansies between realtime monitor and playback - you can select either as well.

Unfortunately it's not that.

Looking up the MIDI monitor thing to see if that sheds any light

If the MIDI monitor shows you messages from 2 channels, you need to come back to that. I’m still thinking you have the transformer set up incorrectly.

[ChamomileShark]

ok, I realised of course I need MIDI tracks for the monitor.

I replicated what I did with the instrument tracks using input transformer - looked at track 1 - it was receiving events on MIDI channel 1, and track 2 was receiving events on MIDI track 2.

However, when I look at what notes are being passed - the actual information recorded in the MIDI monitor is identical for both tracks.

That suggests to me that Reaktor is actually sending the same data on both MIDI channels after all despite seeing the MIDI out set to 2 different channels from the two MIDI out blocks.
