Hi @scarlit.port, welcome to the forum :), hi @Kultschar!
I’ve used the MDUW RAM machines a lot. I cannot say I’m the most original user here but let me share about that. To be honest, RAM machines must be the ones I have most used.
First of all, I’ve used them in a live improvisational context, with other musicians sending their signals into the MD. That allowed me to sample bits of their playing on the go, FXed them and to throw them back in the mix. Or to use them to make up a pattern. The folks liked hearing some unexpected, disguised alter ego of their instruments
In some solo impro sessions, I had kits with -always- at least a couple of R/P machines in order to sample a whole bar of the pattern and loop it while I edit the pattern tracks. To achieve that, the RAM R machine ILEVEL paramteres should be minimized and the MLEVEL should be set above 0.
I used that in a more traditional project too: a rock-electro duo with synths, guitars, vocals and the MDUW as a drummer. I sometimes used a couple of RAM machines to sample the pattern and play it back for some occasional transitions, applying an effect to it: filter, filter sweep, rate reduction etc. It was easier than programming the FX on all the tracks.
I did that in song mode: the RAM R machines was always muted except when it had to sample; the RAM P machine was always muted except during the said transition.
As you said, playing back a whole bar is limited to pitch settings 0, -1 octave or +1 octave if you want to say in the tempo. That being said, with bits of pattern sample and a little programming, I’ve already managed to make something interesting. Just try out.
RAM R machines are also a good way to have external audio signals through the MD track/global effects. You can use the CUE settings on the first parameter page.
Finally, yep, I used RAM machines to sample some audio and send it into the ROM slots.
I should mention this video @Allerian once did, where he programmed a RAM R/P track pattern and let the MD sample a vynile by itself. … I cannot seem to find it…
EDIT: here it is!!
