Hi - does anyone know of a program or app that can generate a random BPM, within a range specified, that changes randomly, over another specified period? For example, the BPM changes every 10 seconds between a user-specified range. Thanks!

To generate sound files or to run as a self tease?
Guideme can do the latter (you could probably do it in TeaseMe as well).
You would just need to write a simple tease tease file with the correct parameters.
I could knock up something for you as an example which you could then customize.

I wrote a small java app that tries to generate and play back random beats similar to what would be found in a CH video. The randomizer is not fantastic but it works. The app also accepts an input file that allows you to 'write' a song specifying what kind of beat, for how long, what kind of sound to output and so forth.
If there is interest i'll try polish it up and post it.

I solved a similar need by generating a set of beat mp3:s with a variable length... like so:
1 sec of 1 Beat Per Second
2 secs of 1 BPS
3 secs of 1 BPS
4 secs ... 5, 6,7,8,9

repeat for 2 BPS and make silent files similarly

Make a playlist in VLC (or other suitable player) with for example 4 copies of all the files. Play the list on repeat and random.

Realise that 9+8+9+9 secs of silence is quite a ... frustrating wait; remove files over 6 secs from playlist... :)

Quite simple to generate in Audacity, place the first beat of each file half a beat from the start of the file (1 BPS => file starts and ends with 0.5 seconds of silence from the beat), this makes the change between speeds a little less jarring.

Would've attached them but seems that 2,5 megs is too much... what are the limits?
