Beat + Melody by Mastazi
With this patch, you get kick, hat and snare using only noise, LFOs from the MOD section and one of the LPGs, so you can still use both oscillators, the EGs and the other LPG for the lead or bass line.
The internal sequencer is not used to sequence pitch, but to control the LPG2 cutoff. A low value in the sequencer step will create a kick sound (due to the LPG's natural decay) and a high value will make the noise audible hence it will sound like a hat (you need a bit of resonance to make the hats more snappy). An intermediate value of about 2 o'clock (as on the 3rd step) sounds a bit like a very, very lo-fi snare. This way our rythm sounds more like a boom bap beat. If instead you prefer a four-on-the-floor beat, just set step 3 the same as step 1.
The other CV of LPG2 is controlled but a sine LFO (coming from the MOD section, so it's synced with the pulse LFO which drives the seq) by doing that I accentuate the closed/open cycle dynamics between beats. In this case (unlike the other CV) I'm going through an EG but as you can see I ended up setting both attack and decay to 0, so you can actually skip the EG if you want, and the sound will be pretty much the same.
Regarding the lead sound: it is driven by an external sequencer that sends gate to EG1's TRIGG and pitch to VCO2's 1v/OCT. The sequence itself, is an arpeggiator in random order mode, the notes being pressed on the keyboard are all from an A minor pentatonic.
VCO 1 is connected to LIN FM and modulates VCO 2. As you can see, I'm sending audio feedback from the carrier (VCO2) back to the modulator (VCO1), feedback was used in classic FM synths like the DX7. In order to do that you need to use a split cable out of VCO2 (the other end of the split cable goes to the LPG1 input) or alternatively you could use a multiple.
I have connected the BBD and turn it up every now and then for creating a bit of variation. Another thing that creates variation is playing with the pitch wheel on the external arpeggiator, in order to detune the sequence.
