You really don’t need an analogue synth at all to produce the kind of heavily clipped/distorted/overdriven sound examples you’ve posted above. Actually, most of the examples you post sound distinctly “digital”. :slight_smile:

Getting to this kind of sound from an analogue source is more about using distortion and overdrive effects pedals and extreme gain clipping (turning the channel gain on a cheap Behringer mixer all the way up can be used very well for this, for example).

You’ve probably already figured out that using the sample editor on the OT for dirty digital clipping works very well?

A reason to keep the A4 might be because you like the sequencer. If that’s not the case, then you might be better of getting something cheaper and a few nasty effects pedals.

Have you tried the Microbrute? The Steiner-Parker filter on the Brutes can probably get you closer to the kind of dirty and metallic sound you’re after, and you can get very crazy results by routing the “mod matrix” outputs at the top right through external effects.

Finally, some tips for getting dirty on the A4:

[ul]
[li]Turn the OSC level all the way up to get some clipping before the sound goes into the filter.[/li]
[li]Try extreme PWM speeds and depths.[/li]
[li]Play around with the sync options; metal sync can be extremely dirty. Don’t forget that you get the best results by changing the pitch of the oscillator synced to using an ENV or LFO.[/li]
[li]Set OSC 1 to “Filter Feedback” and play around with cutoff and resonance on filter 1 for some extreme feedback effects.[/li]
[li]Use the overdrive on filter 1.[/li]
[li]Use the ability to route the output of the previous track into the current tracks (set OSC 2 to “Neighbor”) to increase gain.[/li]
[li]Route the output of the headphone jack back into the external inputs.[/li]
[li]Use extreme LFO modulations (speed & depth) on pitch, amp, filter cutoff, etc.[/li]
[li]Abuse the effects. Especially the delay can be very effective for noisy drone sounds if you turn overdrive up and tweak the feedback.[/li]
