Heyo CSM yeah effects have always been very important I’ve had zillion of FX racks, boxes, pedals etc.
Some stuff I use currently:
Zoom 1201, Moog MF104 Analog Delay, Moog Lowpass Filter, Color Sound Wah Wah pedal, Alesis Quadraverb, Roland DEP-5, Evans ECHOPET, Boss CS compressor sustainer, Nomad Echoes, Soundtoys Echoboy, Filterfreak etc. Audiothing Outerspace…compressor, phaser,flanger vibrato, EQ pedals (Electro Harmonix, Boss, MXR etc.), a lot of selfmade FX racks in Ableton etc.
Roland SRV330 Dimensional Space Reverb - The name makes it sound like a dimensional time portal of esoteric properties, but its a pretty cool reverb very 90s ambient…2 things Roland always had going pretty darn good were their sampler and digital reverbs sound characters, I guess they used the same DA converters and secret sauce?
Roland SDE2500, Boss DE200: These are sort of the same, the Boss being a budget version of the 2500, they both have this looper button which loops part of the delay signal. A very short loop…1 second?Sort of an extremely rudimentary sampler, there is a button called 2x that plays the loop at half speed, its really nice for creating atmospheric pads with weird artefacts.
hmmm any unusual concepts…lemme think
I let my auxiliary effects signal come back to a actual mixer channel with mid sweep EQ etc. so I can ‘filtersweep’ and have more control on whatever fx is coming back…this might be really obvious but I see a lot of people using the standard auxiliary return channels/input which a lot of times don’t have EQ.
Always keep turning the time and feedback knobs on delays for more animated depth
In software put a parametric EQ or filter before or after a delay (I guess before makes more sense…but there are no rules

) and sweep the mid frequency so the delay signal becomes more ‘alive’…
Delay/echo is the most important effect I think, it makes sound become ‘multidimensional’…very much my foundation in effects use comes from listening to dub reggae records imo one of the understructures of techno/electronic music/whatever its called.
They way these dub producers would alter the sound live and see the mixing desk as an instrument is very inspiring and important I think.
