Okay, so my latest session I sat down and made a list as I went of things where I went "man, this would've been really useful." So here they are in no particular order:
-Rallentandos. These are incredibly common in music of all genres and there's no real reason that I should have to manually insert tempo changes bpm by bpm and calculate where they go. I should be able to pick two separate points, create markers, and tell the DAW to automatically rall from one to the other.
-Splitting or Panning Stereo Tracks. So when I get a single track that's stereo, it would be really awesome if I could hard pan each channel left and right instead of panning both channels together (or having the whole thing sit center). Alternately, the way I work around this is to duplicate the track, and then set one to left channel only and one to right channel only, then hard pan them. If there was a way where I could tell the DAW to automatically split this stereo track into two mono tracks (Audacity does this, for example) that would be a big time saver.
-Linking Track FX. Related to the above suggestion a little bit, it would be really cool if I could stereo link tracks for fx, automation, and volume (in order of what concerns me most). For example: my client sends me a stereo guitar track. In a perfect world, I can hard pan the channels without having to split it, but if I do have to split it, it would be really helpful to tell the DAW to link those two tracks so that any EQ or compression or whatever I apply to one track gets applied to the other. Volume and automation would also be helpful because presumably 90% of the time if I'm linking tracks I want them to behave the same way across the board. Again, this would be a massive time saver. I know that technically I could just save my chains on one channel and move it to the other, but that's a cluttering up of my presets (as a minimalist, I dislike that idea) and it's really just an extra step. Workflow. Time is money (literally in this case, all the things I'm listing could cut my work time down by as much as an hour or more, saving my clients money and freeing me up to work on other clients).
-Copying/Dragging FX Chains. On that note as above, say I've got multiple guitar parts but I don't want to link them, but it's all the same guitar/tone/player/etc so I do want to use the same FX chain at very least as a starting point to be fine-tuned. ProTools, Cubase, and I think a couple others all have the ability to just drag and copy FX chains from one channel to the other. This would be another massive time-saver. Again, yes I could just save the chains as a preset, but that's still an extra step and it clutters up my preset list.
-Dragging Automations. So this one isn't really a big deal but it is one of those "man that would be sweet" things. In ProTools and Cubase, I see users who can highlight a section of automation and then drag it up or down to make adjustments just like you would with a fader or knob rather than right-clicking and adjusting the volume numerically. This would be awesome for when you're making fine-tune adjustments and you're trying to play around and find just the right level. Rather than "right click - 2 db," too loud, "right click - 1.5 db," still too loud, "right click - 1 db," too quiet, simply drag it around slowly until you get it right. (And of course, keep the option to type in a specific volume if we want it, that's a huge help more often than not.)
-Multiband Processing. Last but not least (for now), and again this is another "would be cool" things. One of my friends has Ableton, and in Ableton there's an ability to apply FX on bands. Think like a multiband compressor - you set the bandwidth (say "0 Hz - 250 Hz" for bass) and then you can apply master fx to JUST that frequency. He uses it mainly with metal to apply more transient control to the low end, and it really helps a lot. That kind of stuff would be really neat and give users more control.
That's all I've got for now, I'll post as I come up with more. I just want to say Mixcraft is awesome, I've tried other DAWs and for the most part I hated them. Mixcraft is super user friendly. I use it professionally in my studio and when I share mixes with other pros for feedback I'm definitely holding my own against ProTools, Cubase, Reaper, you name it. Just offering my suggestions to help improve the product and make it awesome for users of all genres and levels
