i too am using one of the mm’s as an effects box. its quite overwhelming the number of effects we have to explore, especially in the airwindows brand. i have really enjoyed and gotten some success recently out of the following modules:
DELAY-
texture synthesizer (aka clouds) - this one is like a holy grail. it also has a nice reverb built in, and could be pitch controlled by a keyboard
kocmoc DDLY - very cpu friendly so i can use a whole lot of them!
airwindows tape delay - has a nice tone imo
4ms DLD - very powerful and i don’t fully understand it yet, but it seems great for doing live looping
REVERB-
airwindows galactic - very cpu friends for a stereo reverb, i usually put this on the end of my chain. you can do really big reverbs with this one.
plateaux - uses a lot of cpu but it sounds really nice when you want to play with the various knobs on it (whereas galactic can be a bit glitchy when you are turn it’s knobs).
EQ-
i dont feel there are a lot of good options, but ive used the following:
bog seq
bog PEQ - i haven’t really messed with this one much, but it seems useful?
COMPRSSION-
i also dont feel there are yet a lot of great sounding options in this category
bog LMTR - its not the cleanest sounding one when you really push high volumes into it bit it works ok for a brick wall limiter
bog CMP - same story as the LMTR
CREATIVE/MANGLING TYPE FX -
4ms pitchshifter- you could control the pitch of this with a midi keyboard
4ms detune - this can create a nice warbly vibrato
airwindows glitchshifter - does cool things to the sound! but maybe a bit too glitchy sometimes
again want to mention texture synth/clouds is such a great granular mangler
for tremolo, we dont have a lot of options, i think there is one by airwindows but i usually just put a bog LLFO into the fundamental VCA for tremelo effect.
FILTER-
bog LVCF - nice cpu friendly
4ms bfp - very cpu friendly bandpass one
nano font - a nice cpu friendly feedback style filter
DISTORTION-
i don’t know if ive found one that i really like, but the airwindows drive is decent. air windows has a ton, i really need to research these more.
UTILITY-
bog walk - creates really nice smooth random lfos. i use this all the time to control the parameters of various fx ones
ones i haven’t tried but have heard good things about:
bog PEQ14 vocoder - kind of a cpu hog, but seems like it could be great for vocals?
sorry that’s all probably tmi, but those are the fx modules i really have enjoyed exploring and running various sound sources through recently.
