In the Pulp tracker, there is some difficulty isolating channels when making changes to individual synth voices.
When wanting to "solo" a track, currently you need to set each other channel's volume to 0, which is not ideal given track volumes are currently not generally all going to be a set number.
This would make the tracker usability quite a lot quicker, as you could mute/solo synths on the fly without overwriting the synth's currently set parameters.
