Play only one instrument (or several selected instruments)

• Nov 11, 2016 - 02:49

A cool feature - assuming it's not already present - would be to allow the playing by the synthesizer of only certain selected instruments. For example, you could play only a clarinet's part. Or you could play only the trombone section. One way would be to select the instruments you want to hear by highlighting them and then hitting Enter (rather than spacebar). The current method of selecting parts is to click on one measure, then click on a measure directly above or below so that all the parts between those two clicks are highlighted.

If you wanted to add the ability to select parts that are not contiguous - for example the bass and lead trumpet parts - it would be necessary to add the ability to use the Ctrl key instead of the Shift key to add non-adjacent parts. In other words, Click on a measure in the bass part, hold down the Ctrl key, then click on a measure in the lead trumpet's part, so that both are selected (but not the instruments in between), then press Ctrl-Spacebar (or whatever) to play only those instruments' parts, starting with the highlighted measure.


If I understand you correctly, you are describing an existing feature - see View / Mixer. You can solo or mute instruments as you wish in one convenient window.

Didn't know about that feature. The only downside is that you have to go back into the mixer and turn everything back after you're done, and there's the potential for accidentally neglecting to return the mixer to its original state. But it will certainly do the job.

I think it would be a little faster to select the instruments directly, without bringing up that mixer window. Click one part first. Then if you want other instruments to play along with the first, select them as follows. If all the desired instruments are contiguous, hold down the Shift key and click another part to select all in between, as we do now - or if not all the instruments you want to play are contiguous, hold down the Ctrl key and click the individual parts one by one, so that there could be multiple blue highlight boxes, not just one tall one. Then hit Ctrl-Spacebar (or whatever) to play only those instruments selected. If you hit plain Spacebar, it would play all instruments (except for those muted in the mixer, of course) as it does now.

Whether it would justify the additional programming work, I don't know. Worth considering for a future version?

Well, a mixer is generaly how you'll do that anyway, it's like most DAW you'll ever work on, as you can at least see which track are soloed/muted. To make it more easy to access they programmed a shortkey (I think it's F12 ;) ).

Hope it'll do it for now! :)

If you are doing this sort of thing often, simply leave the Mixer up. And the advantage is, the settings stick even while you make selectiosn for other reasons. Having the selection mechanism double as the way to specify which instruments play would be severely limited in comparison. I'm not seeing any possible advantage, only disadvantages.

I write again to emphasize how cool a feature what I had suggested before would be. Let me try to explain it better this time.

1. You want to play one instrument only. You select a measure of that instrument and hit ENTER (rather than SPACEBAR) and it plays only that instrument from that point. You don't have to bring up the Mixer window, scroll to find that instrument, and click on Solo for it, then once you're done, go back in and unclick Solo. One mouse click and one keypress and it plays. Much faster, and without the danger of forgetting to restore to the original.

2. You want to play the trombone section alone. You select a measure of the top trombone staff, hold down the SHIFT key, then click directly below on the measure for the bottom trombone, thus selecting the whole section, then hit ENTER, and it plays the whole trombone section from that point. You don't have to go into the Mixer and click Solo for each trombone, then once you're done, go back in and unclick them.

3. You want to play the lead alto and the string bass only, or the trumpet section and the rhythm section only, or any combination. This would require adding a new capability - that of selecting two or more measures which are not adjacent. The best way would be that once a measure is selected, hold down the CTRL key (rather than the SHIFT key) and click one or more additional instruments above or below, which would put a blue box around each of the selected measures. Then hit ENTER and it plays just those instruments.

I don't mean to be a pest and fully understand if this would all be too much work, but I'm convinced that if implemented it would make it a lot easier for a composer or arranger to hear individual instruments or sections, if that's important to anyone. The mixer box is a bit cumbersome, in my opinion, although it certainly works fine, and that option would still be available if you want to work on the same group of instruments over a period of time. Thanks for listening.

I like this idea. It makes sense. You should be able to shift select adjacent instruments or ctrl-select to add non adjacent instruments like many other types of programs. ENTER does not have to be the way to activate this feature if that conflicts with another default setting. It would be able to be user defined like other shortcuts.

This is basically how I expected the playback to work, as I previously used Sibelius quite heavily.

Using the mixer is a bit of a PITA for quick testing of internal harmonies etc. But I appreciate the code change to implement this might be quite difficult.
