I just want to point to these superb Arturia ARP 2600 V3 videos:
Part1: Overview (Synth Parts, GUI, Browser..
Part2: Presets
Part3: Synth Overview (Pre-Patching, EnvFollower, RingMod, VCOs, VCF...)
Part4: Envelope Follower
Part5: Ring Modulator
Part6: Oscillators (Spectrum+Freq analysis, PWM, Tuning, OscSync, FM, xMod)
Part7: Filter (Sound sculpuring, Filter types, Filter Modulation..)
Part8: Envelopes + let's make common sounds
Some videos are short (EnvFollower), others quite extensive (Filters, Envelopes).
But all are made in a very likeable way - just the opposite of these YT wow-I'm-cool guys (PointBlank et al)..
Highly recommended
