If any of you followed my Alesis Micron - Patch a Day blog, you may recognise the concept of this week's patch - a melodic patch using no oscillators. How? Read on...
The first thing to do is to go to the mixer and turn off both oscillators. The sound for this week's patch will come solely from the self oscillation of the resonant filter (both the LPFs will work for this). Close the filter completely and crank up the resonance to 127. To be able to play a melody with this patch you will need to assign keyboard tracking to the filter (how much modulation you apply will affect how "in tune" your patch will be). Further tuning can also be made by opening the filter cutoff. By how much is up to you, experiment! I have found that playing with the resonance level while playing the pitch can cause problems without some noise so I have added this in the mixer.
To shape the sound I added a bell like amp envelope and then applied the arpeggiator. The effect is most pleasant, amplified with the use of delay in my opinion.
Here are the settings:
Voice: SYT, SGL, PLY, ---, --- (unchanged)
Pitch: 0, 0, 0, 2, 5 (unchanged)
Osc 1: SAW, 0, 0, ---, --- (unchanged)
Osc 2: SAW, OFF, 0, 0, --- (unchanged)
Mixer: 0, 0, 127, ---, ---
Filter: 12L, 0, 127, 0, 46
Filter EG: 0, 64, 127, 0, ON (unchanged)
Amp: 127, CNT, OFF, 0, --- (unchanged)
Amp EG: 2, 88, 127, 77, ON
LFO 1: TRI, OFF, OFF, 10, --- (unchanged)
LFO 2: SIN, OFF, OFF, 70, --- (unchanged)
Patch 1: MOD, NOS, -63, ---, ---
Patch 2: LF2, PTC, 0, ---, --- (unchanged)
Patch 3: LF1, CUT, 0, ---, --- (unchanged)
Patch 4: LF2, CUT, 0, ---, --- (unchanged)
Mod FX: FLG, 20, 0, ---, --- (unchanged)
Delay: L-R, ON, 1.8, 88, ---
EQ: 320, 0, 6.0, 0, --- (unchanged)
Arpeg. A: 120, 1.16, 80, UP, 2
Arpeg. B: OFF, 0, ON, 8, --- (unchanged)
You'll notice that I've assigned the mod wheel to the noise level. When you're playing the arp try playing with the resonance, filter cutoff and noise level to get some cool glitchy effects when combined with the delay. Further fun can be had if you route LFOs to the cutoff or add a filter envelope. Get wonky!
