Region gain/clip gain and input trim

yes, it's **clip** gain in qtractor parlance :)

you can find its setting on, you might guess it right, on Clip > Properties... menu:
- on audio clips: it's accessible right from the main canvas view (menu Clip > Edit... or just double-click on it).
- on MIDI clips, that will stump over the the so callled MIDI clip editor aka. piano-roll first, and only after that you get to File > Properties... alright for that matter :)=

let me tell ya also, if you have the patience and some reason to think about all this ardour vs. qtractor conundrum...

first on all things, ardour and qtractor are not, never were, close in development, concept, nor in design, whatsoever.

you might reckon that ardour follows (very closely, shall i say) former digidesign's--now avid--protools concept. thus, also obviously, it's modeled on old and analog mixer console surfaces from the traditional recording studios of yore;) my terms though. all that to say the terms you use--say like, "input trim"--are just resemblance of those days.

it's just that some many people do learn to do new things the old way, which is a plain contradiction to progress and what not, if you ask me.

ask yourself: is that, or can you call it, innovation? of course not.

anyway, technically, input trimming should be of physical audio device responsibility or setting--read or check your soundcard manual or front-panel); on the digital age, input trim gain is an analog concept and thus it shall be put before any A/D (analog-to-digital) stage, so look into your hardware first.

on the other hand, qtractor followed the cakewalk's pro-audio series just in case you're too young to know--there's no offense here, just a fact i wished to share so please don't get me wrong--but the thing to have in mind is: qtractor is a digital age tool: it plays the modular game, although in a hybrid form perhaps (yes, it does plugins, which is nay saying on a pure modular terms; qtractor doesn't mean, never meant to replace any other, so called digital-age tool.

now, you may also watch that ardour, or any other DAW for that matter, commercial or not, are willing to take and grab the whole show. your show ;)

that's the monolith stance, one that is pervasive on all other places and views, the all-in-wonder-do-it-all walled garden and premises, and that's quite understandable from any capitalistic and wannabe profitable business you can think of, no matter if it's free, open-source or else. it's a business decision choice. and that's about it.

qtractor is free, will still linger on to be free, open-source software, and to be fair with everyone else, it will be a Linux-only application for the time to see (and hear:)). at least while under my watch :)

shall i get my mantra and spell here and again? that probably would make both of us sick to death if not just to pure boredom :) but nevertheless:

a. qtractor is a sequencer with some DAW features;
b. ardour is a full-blown DAW with some sequencer features.

dixit ergo.
