[linux-audio-user] midi automation and scripting tools?

Hi List, I'm looking for tools that can do things like this to a midi file: "take all the kick drum notes from bars 9 to 16 and shift them forward in time by 2 ticks" or "take all the notes that occur on beats 2 and 4 of bars 1 to 32 and shift them back by 4 ticks" or "shorten all notes in track 2 by 10% with a minimum length of 1/64" or "for all notes in track 3, insert a pan controller with a value equal to "pitch - 36", just before the note on event" I'd also like to be able to do the usual audio automation and simple effects applied to midi: compression/expansion (of the velocity values), echo, pitch shifting, fade-in/out, LFO-pans, ... Now, I've collected all the midi code I can find ranging from the various python midi modules, c and c++ midi libraries, haskore, clm, and so on, and it doesn't seem to me that any of these tools make it easy to do the things I'd like. The main problem seems to be that existing programs either view things from the "musical" perspective of bars/beats/notes etc, *or* the midi perspective of time-stamped events. But no programs I've found seem to understand and be able to handle both views. For example, selecting notes based on their position in bars/beats, but then referring to their length in ticks, just doesn't seem possible with any of the software I've seen. Up til now I've been using my own python code to do some of these things, but the code is getting unwieldy and buggy to the point where I need to either: 1. Find a replacement, or 2. Bite the bullet and rewrite the code from scratch with the intention of releasing it when it's fit to be seen in public. So, does any body know of any tools out there that can *readily* do these things? I'm happy with a scripting-language type approach, or a gui, or a combination. Thanks in advance.
