So, Let me explain my usual workflow in brief.

Below is a pic of basic project template, because regular is much more complex to explain.


(RC here means RapidComposer)

I have Track 1 for midi input only, record option is disabled on the track.
Output from this track is then routed to

Track 2 which has RapidComposer, so basically the signal runs through RC and then it is routed to the other tracks, Like Bass, Lead and keys etc.

Track 3 is for Midi Capture only,

Sometimes i use scaler or Reacontrol on Track 1 to lock the notes into scale. The signal is then routed out to external virtual midi port and then back onto Track 3, because Reaper does not capture output midi, only input (retrospective midi, there is a separate post for this http://audiosex.pro/threads/looking...midi-capture-record-plugin.70292/#post-706590)

Track 1 → Track 2 (RC) → Other instrument tracks
↓ Track 3 (Midi capture)
↓ ↑
Out to virtual midi port =>

So, back to the topic I use RC only to preview the instrument.
When i say preview, this work flow doesn't require a track inside Reaper to be armed every time to play it. Just clicking the track inside RC (as in Pic) sends the signal to that Track. IOW to listen to what is being played.

i mostly use Retrospective midi capture as a record feature, capture and clear frequently and rarely use record, except for audio.

I have a Script with a shortcut to open and close RC, I use RC to select the track which routes the signal to that specific track with instrument, without selecting or arming in Reaper, like mentioned above, that's all i use it for these days.

The problem is, sometimes RC gets laggy and have issues with hanging notes, and unnecessary waste of resource when working with bigger projects.

So is there a plugin or a tool with a feature like this, like just to select a track or in this case a midi channel, without arming or muting other tracks, which sends signal trough that channel to the track.

Thank U

not exactly sure what you're trying to achieve such complicated way,
just put a folder track above (routing destination basically) and there right-click and choose to record MIDI output



also you can use some MIDI filtering, experiment with anticipative FX processing setting in Reaper,
you can also use ReaStream plugin to create localhost network to send+receive MIDI (and, or audio)

 

Hi @tzzsmk, thank u for responding.

What i'm looking for is an alternative for RC especially for the routing/wiring functionality, if u have used it u ll understand more clearly.
What it basically does is, it has this internal wiring/routing. When u route a midi port with 16 channels lets say "internal midi port 1" to the track which has RC, the signal goes into RC and then u can select a track inside RC which basically routes that signal from "internal midi port 1" to that specific track which has a channel assigned to them. It works like arming the track but with just one click.

Lets say Track 1 in RC which is Bass from the above pic. which has a channel assigned to it "channel 1" in this case, which is then then routed to the Bass track in Reaper.


Of course i can auto-arm the tracks in Reaper just by selecting them, but it creates more mess when i try to capture midi "retrospective midi" it just splashes midi all over the place.

There are midi filters, i use code fn42 MIDiChFilter but it doesnt work. It just filters out the channel.

 

I read this three times and I still have no idea what you're trying to accomplish or what you need to get done.

 

Lol, Never thought it would make much complicated to understand.
Like mentioned b4, i dont know if u have used RC. but in short im looking for a plugin with a similar routing capability like RC. It has a way of routing midi just by clicking the track.
Let me know if u still don't understand or which part u don't get.

 

So all you want is a script that you put on a track that receives MIDI. When you open the script, you get a window with buttons that say:

Channel 1
Channel 2
...
Channel 6

and clicking on those buttons changes all incoming notes' MIDI channel to the button's number?

Yes absolutely correct, Thank you.

and yes route that incoming midi data to the channel/track that i clicked. But, without muting or turning off any of the other channels. Like ive mentioned b4, MIDIChFilter works only for filtering or turning off other channels, it does not redirect or route to a specific channel no matter how i assign it in Reaper.

I searched for a script but there wasn't any at-least to my knowledge. Actually that RC's feature is amazing, i dont why ppl havent looked into it yet. The signal i can route through it in and out is astonishing, Hell i could even route a signal from my Washing machine if possible.

 

So like this but with buttons? (save as something.jsfx and add to Reaper as with other effects)

Code:

desc:MIDI Channel Picker

slider1:1<1,9,1>MIDI Channel

in_pin:none;
out_pin:none;

@init
channel = slider1 - 1;

@slider
channel = slider1 - 1;

@block
while (midirecv(pos, msg1, msg2, vel)) (
      midisend(pos, (msg1 & $xF0) + channel, msg2, vel);
)

 

Yes, thank u dude. it works the slider works to pick the channel as expected. i named it as "xorome - MIDi Ch picker"

what to do instead of slider there are various channel listed one below another, like in that pic above of code fn42 filter, without 'all' 'none' buttons which is not necessary, but instead there is a mute and solo besides each "channel", is it asking too much?

Edit: i changed 9 to 16

Code:

slider1:1<1,16,1>MIDI Channel

I'll look into how to make GUI buttons in Reaper tomorrow.

You want the mute/solo buttons to mute/solo notes coming in from those specific channels?

 

Thanks again dude
i was looking into tat too. https://geraintluff.github.io/jsfx-ui-lib/tour/3 - Controls.html
https://admiralbumblebee.com/music/2018/02/08/Write-a-Reaper-MIDI-JSFX-from-scratch.html

S just in case if mutiple channels has to be selected. And we cannot say "coming in" because its and should be omni, just for the channel that is selected, which is going out.
Lets say like this

Clicking "channel" activates that channel when none is selcted theres no output to any channels, but when two or more selected we can make use for mute solo

Edit: Checked it thoroughly works like a charm. Is it possible to add a function to send "all notes off" when the channel is switched, because when moving the slider switching the channel it leaves hanging notes IOW it leaves a "note on" msg.

I added GUI buttons. Only the channel picker buttons work at the moment. I'll look into M/S and note-off-on-channel-change tomorrow. Please test.

Code:

x = 8; y = 8;

mouse_cap_p = -1;

ch_state = 0; mem_set_values(ch_state, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
m_state = 16; mem_set_values(m_state,  0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);

  ) : (
    gfx_set(0.1, 0.4, 0.3);

  gfx_rect(x, y, w, h, 5, 1);
  gfx_set(.95, .95, .95);

while (i < 15) (
  #label = sprintf(#, "Ch %d", i + 1);

  draw_btn("M",    ch_button_x[i] + 65, ch_button_y[i], 28, 25, m_state[i]);
  draw_btn("S",    ch_button_x[i] + 97, ch_button_y[i], 28, 25, s_state[i]);
  i += 1;

((mouse_cap == 1) && (mouse_cap_p == 0)) ? (
  i = 0;
  while (i < 15) (
    ((mouse_x >= ch_button_x[i])  && (mouse_y >= ch_button_y[i]) &&
     (mouse_x <= ch_button_xx[i]) && (mouse_y <= ch_button_yy[i])
    ) ? (
      ch_state[i] = !ch_state[i];
    );

    i += 1;
  );
);

mouse_cap_p = mouse_cap;

@block

Fantastic.. i will test and get back..

 

@xorome, checked works good like b4.

but
- when hittin play changes back to "ch1"
- there is a minor flickering in the ui i dont know what was causing that. happened couple of times but wasnt able to recreate it after a while.

Changed a couple of things

to

Code:

while (i < 16) (

Code:

(i % 5 == 0) ? (

to

Code:

(i % 8 == 0) ? (

And tried to adjust height and width by

Code:

@gfx 415 163

to

Code:

@gfx 279 260

couldn't get to the adjust width properly.



- Is it possible to select only one channel when clicking, and only when using ctrl+click we can select multiple channels, may be that might be used to changing the channel by arrow keys on KB or by using a foot pedal or smthg.

 

Doh, fixed.

I think there's a minimum width. Not sure it can be helped.

Yeah, I added that.

Left click = Activate channel and deactivate all other channels.
Ctrl+Left-click = Toggle an additional channel.

I added the M/S buttons:
Left click on M/S: Mute/Solo an additional channel.
Ctrl+Left-click on M/S: Activate channel for M/S, reset M/S on all other channels.
(The other way around from channel buttons)

I added note-off-on-channel-change as a checkbox. I made it so that it only sends note offs when you are activating a single channel, not when adding more channels.

@xorome Be careful with posting useful and working scripts for Reaper on demand and in public, this could easily end up in a full time job.

IOW, absolutely great what you're doing for other members here.

 

@xorome thanks a ton dude, works perfectly,

That was a additonal bonus and brilliant, never thought about that.
Mute and solo works perfect.

I just had a look into tat 2, its like fixed, all the jsfx plugins have this width. U r right. I guess its tr for the options on top like parameter, and the preset box.

I was playing with it for a while. Like on the earlier post, just changed it to 16 tracks from 15, moved the checkbox,
Here,



However "note off on channel change" seems to work only on channel 1 or is only directed towards channel 1 not on other channels. But its ok.
