Modular synth is one of the thing that I wanted to learn but It seems complicated to start to me. To step out the comfort zone, I used VCV to create the piece. VCV is a virtual modular synthesiser programme where they are open sources, therefore, they have a lot of difference modules in their library. I used multi-head sampler oscillator called MusicalBox by NYSTHI to play all the recording I choose from the field recording trips and I used BlackHole to send all tracks’ output into Ableton Live.
The real challenge is how to use control voltage to create the forward and backward effect while gradually increasing the speed of this process. At first, I found a 31 steps circle sequencer which I thought it would work to create this effect. But the problems is when I use sequencer, the differences of every steps can be hear which lost the graduate moving effect.
Finally, I found just go back to basic and use a slow LFO to create this effect. Firstly, connect a slow normal LFO to the speed of sampler oscillator, when the LFO is in negative, it would reverse; when positive, it would go forward. Then connect that LFO into a clock and control the modulated the clock speed with another slow LFO, however, the cycle of normal LFO is not long enough for that. Eventually, I found a Seriously Slow LFO by Frozen Wasteland which can create whatever minute long LFO and I feed this into the clock to module the speed and gradually increase the speed of the first LFO.
