I barely ever create patches from scratch. I’m more interested in making music (as in composing) than in making patches, so I only occasionally sit down and build from scratch to learn.
What I look for in a synth is a mix of capabilities and ready-to-use stuff. I fall in love with the bells and whistles, but if I can’t find close-to-usable patches, I probably won’t use the thing. (This I learned after buying too many synth plugins…)
So, my workflow is having a rough idea what I want - like do I want it to play fast notes… maybe a preset tagged as plugged will do…? So I go through and try to find something. Either I find something close or better. Then I tweak. Effects, cutoff, envelope settings. How much drive? What kind? Does it bounce or does it sound flat?
I will then likely approximate something but it’s a bit hit-and-miss, limited by what I can do.
Since I divide my time between making electronic music and the guitar and what not, I don’t really find the time to focus only on synths. But for example with guitar it was the same for a long time - I would often use presets, then learn to tweak. These days I often start with an amp and build from there. But for the most part, a guitar signal chain is easier to grasp than making all kinds of synth sounds. Still, it took me years to go there.
(Also, trying to find learning material for synths is… bad. Not what the controls do. But how to make patches, patching strategies, how to achieve certain sounds…)
To give two examples… One of the last synths I tried was Minimal Audio’s Current. Endless marketing, can do this, can do that, they support it with lots of this and that… so I did the trial. I go through preset after preset and hear nothing I like, nothing I can use. Too fiddly, too atonal, nothing simple and straight, too much showcase stuff… so they certainly didn’t make that sale.
On the other hand, I have Reveal Sound Spire. It’s not the most complex synth, but I recently use it a lot because it has a damn good factory library. It loads presets fast, so I can cycle through sounds quick. Tweak the two envelopes, play around with the effects - and I hear what I had in mind. I’m not sure I even touched the oscillators as of yet. I do know my way through a lot of the other parameters, though.
Similar things can be said about SynthMaster, a little less about Pigments (too many over-the-top presets, very heavy on effects). I also like browsing through the Arturia presets with Analog Lab, even though its usability is abhorrent (loads for ages, getting to edit presets is finicky, each session I have to reopen edit mode…). But for browsing the catalog it’s good enough.
When I sit down to make a patch, I often start making something on Pigments or pick a synth and try to learn it. I love modular synths like Voltage and stuff like Reaktor, but I don’t have the time very often…
