Amazing patch man! In detail very simple, in harmonics very complex! This patch is amazing. Very easy to follow. The one thing i don't understand is the sequencing of the fold. Is it from pamelas or from waters? Thx and best regards
Thanks! So all the pitch sequencing is from Water. The first output of Water is quantised and sent to DHO voice 1, which gives one ‘harmonic triangles’ layer plus I’m taking its sine, which runs through the folder and LPG. The second Water output (which is just a copy of the same sequence 3 steps out of phase) goes to DHO voice 2, which gives the other ‘harmonic triangles’ layer plus I’m taking its pulse, which goes to the other LPG. The *rhythm* sequences for the sine and pulse voices (i.e. the triggers that feed the envelopes that open the two LPGs) come from two channels Pam’s Pro. Hope that makes sense!
Can you explain to me a little bit more slower how you're doing the pitch transposition? I understand that all sounds are coming from the same VCO, so I guess you're putting that slow modulation from pams to change the root pitch of the VCO, is that it? Are you mixing it with other pitch modulations for the full transposing effect? I understand that the first section of melodies you're doing from modulating the cv inputs in each of the octaves of the 2 vcos. Are the other 2 melodies both coming from Water? Sorry if what I typed is hard to understand, I'm just trying to follow my train of thought while trying to understand it, and its messy hahaha
No problem, I'll try to explain what's going on: Water's output 1 goes through a quantiser and into one input of a precision adder. A slow (/32) square from Pam's, set to 12% level and also quantised (so the voltage is equivalent to exactly 7 semitones), goes into the other input of the adder. The output of the adder goes into V/oct of VCO 1 in the Dual Harmonic Oscillator. So this is basically getting the sequence from Water, which (thanks to Pam's) is transposed up 7 semitones for 4 bars out of 8. VCO 1 in the DHO is then providing two 'layers' - the first is the mix of the four triangle harmonics in the main unit. These all follow the pitch received at the V/oct input but are one octave apart, and they're having their levels independently controlled by 4 of the 8 LFOs coming out of Filter 8 (patched to the internal VCAs on the DHO), so they fade in and out in order, but their timing isn't synced to the main clock/sequencer. This gives the kind of rippling octave effect that makes a basic melody sound much more complex ;) The other layer provided by VCO 1 is the sine wave that's available via the DHO expander. This passes through a wavefolder and LPG and plays the very simple underlying sequence that you hear right at the start of the video. Then I'm taking output 2 from Water, which is basically the same sequence but 3 steps out of phase with output 1. That runs through a separate quantiser and precision adder, where the same channel of Pam's is used to transpose it in the same way, and into VCO 2 in the DHO, which is also tuned up a fifth from VCO 1. VCO 2 also provides two layers - another layer of rippling octave harmonics with the levels controlled by the other 4 LFOs from Filter 8 patched to the internal VCAs; plus the pulse wave from the expander which runs through an LPG that's triggered using a Euclidean pattern. The key things here are the two phased copies of the same sequence that are provided by Water; tuning the two VCOs inside the DHO so that they're 7 semitones apart; the transposing by 7 semitones for 4 bars out of every 8, provided by Pam's, and the use of Filter 8 as a free-running LFO with 8 phase-related outputs that control the levels of the 2 sets of 4 octave harmonics in the DHO.
There are two oscillators in the DHO, and each has several outputs. So the four layers are the triangle harmonic mix from VCO1, the triangle harmonic mix from VCO2, the sine output of VCO1 (through the wavefolder) and the pulse output of VCO 2. The levels of the first two layers are controlled by LFOs modulating the internal VCAs; the sine and pulse each go through an LPG opened by envelopes. There are only two pitch sequences, going to the two V/oct inputs, but each one is effectively driving two layers. I walk through all this in more detail in the video 😉
