creating mono bass synth with AE modular?

I think filters are very important indeed. When I first received my AE Modular I also had a feeling that creating bass sounds was different somehow. I believe it was because I wasn’t used to the WASP and NYLE filters. The WASP design for example loses bottom end with increased resonance (similar to a 303 filter). To get a thicker bottom end, mixing a triangle or sine wave with a pulse wave can also work well. You can of course shape a pulse wave into somewhat of a sine with a low-resonance LPF.

EDIT: Envelopes are important too to shape the filter sound over a note’s time. So try adding a decay ENV to the filter cutoff as well as to the VCA.

Thanks for the tips
Yeah I have WASP filter and this is not the right choice for beefy bass sound.. Perhaps will have to work more on DIY filters or just grab Nyle filter from AE shop.
And will have to test mixing pulse wave with triangle as advised.

Used my lunch break to film a quick bass sound demo (decent speakers or headphones necessary of course):

btw, NightMachines, there's something out of topic, but still - is it "normal" that the output signal from a master module is very low? If I plug it to my mixer I can barely hear anything.
I've got a very simple passive noise-cancelling gadget from eBay with mini jacks for input and output, if I plug it before sending the signal to the mixer - it sounds way louder than without.

Yeah I've tried with a few different setups and cables. Still the same. I bought this Master module (pre-installed in a rack) back in 2018, maybe there were some issues in a certain batch with these modules? had you heard anything related to that? Maybe I could just try to open the module and check all the connections myself.

EDIT: OMG! NightMachines! I'm dumb. All the time I was using only stereo mini jacks from Master module. Even if on the other end it's mono - it still doesn't work (well it works, but very quietly). Now checked with eurorack cable - all works fine - loud and clear. And I've spent more than a year thinking that it's "ok"...   

Thanks TNM for the video.

There was 1 thing I was thinking about, you take the normal VCO as base for the bass.

But the 2OSC/D has a sub-octave output, would that not provide a good base for the bass ? 

Yes I wrote it a bit above, mixing the sub oscillator works great to give some punch to a bass sound.

From my experience Kick can be used to create realy fat bass. I send it to Wavefolder, Wasp filter (which CV was modulated by SEQ16) and Delay plus long envelope. This enhance the possible use of Kick which may add really nice sound

I'm not sue which module are You reffering to asking about old or new version, nevertheless all modules I've mentioned are early versions. 

I like going out the ae modular into distortions. I was happy to hear the filters have a lot of sweet spots and even tiny adjustments to env/ filt/ vca can really change the sound. I like the fact the bass is a little bit tighter to my ear on the ae. I think it's a good sound allows it to sit with other synths. I also like sending 2 or more oscs to the mixer to detune them. I send all the outs of the svf to a mixer and balance the sound. 

I've turned AEM into bass synth and I've got REALLY satisfying bass sound with many modulation possibilities sending buffed up square wave into two different routings with different means of modulation along the way, to combine them finaly in the mixer. One was send to wasp and wavefolder the other was sole wasp (another one) or combined with Nyle. With the knob action here and there it made a wide scope from deep sub-bass through more clean sound and then rich, fat, dirty, juicy, plucky sound until full blown acid resonance. No external FX, just the touch of DELAY module. Check out my AEM bass feast 
And here are all the details of the patch:


2OSC {pulsewidth at 12 o'clock/ freg1 at 2 o'clock} sawtooth -> VCO cv



VCO {mod at 3 -switched to freq/coarse freq at 7/fine freq at 12/pulsewidth at 9} square1 ->WASP1 in

VCO {knobs as stated above} square2 ->WASP2 in



LFO1 {switched on fast sawtooth/rate at 1/pulsewidth at 10}sawtooth -> WASP2 cv1



LFO2 {switched on slow triangle/rate at 5/pulsewidth at 7} triangle ->BEAT DIVIDER clk



WASP1 {freq between 10-12/cv between 9-12/resonance between 7-5} LP -> 2VCA in1



WASP2 {freq between 10-12/cv between 9-12/resonance between 7-5} LP -> 2VCA in2



ENV {attack slightly past 7/Decay at 10} out1-> 2VCA in1

ENV {knobs as stated above} out2-> 2VCA in2

ENV {knobs as stated above} out3-> LFO1 sync



2VCA {cv1 at 5/cv2 at 5} out1->WAVEFOLDER in

2VCA {knobs as above} out2-> NYLE lp in

2VCA {knobs as above} out2-> 3VCSWITCH 1a



NYLE FILTER {lowpass,bandpass,highpass, cv1, cv2 at 5/frequency at 10-12/resonace at 2- sligthly before screaming} out->3VCSWITCH 1b



BEAT DIVIDER {div at 1/32, triplet} out b -> STEP10 clk



STEP10 {set to 10} 10 -> SEQ16 reset



SEQ16 {cv range 2,5-5/ knobs as on the photo in the link} cv -> VCO mod

SEQ16 {as above} gate -> ENV gt1

SEQ16 {as above} accent -> WASP1 cv1



WAVEFOLDER {drive between 9-3/shape cv at 8/shape at 12) out -> DELAY in



DELAY {delay time at 12/feedback at 7/ dry-wet between 9-11} out -> MIXER4-4 a2


3VCSWITCH io1 {latch switched manualy as gate trigger} -> MIXER 4-4 a1


MIXER 4-4 {level a1, level a2 at 7-5} out a ->MASTER audio1 I/O

MIXER 4-4 {as above} out b ->MASTER audio2 I/O





Unexpected part of the patch was pitch control of the melody via mod knob on VCO, but couldn't get really low bass sound by patching cv SEQ16 output to usual CV inputs of VCOs, nor wasn't able to play melodies sending it to the WASP cv, so I've accidentaly found another way to do it .

The BEAT DIVIDER combined with STEP10 was used to expand the length of the SEQ16 sequence by resetting the sequencer after every 20 steps. Of course it was adjustable by BEAT DIVIDER resolution settings, but I left it untouched during play. I like and often use this trick. 
I was amazed by the wide palette of bass sounds, I think everyone should find a sweat spot to their liking within AEM bass range. Another surprise was that without using KICK, which was my usual way to get bass sounds I managed to carve very deep low sound. (I would say it bears some similiarities with DAF sound!) One of the routings wasn't even going through WAVEFOLDER and still was able to produce valuable contribution to the bass variety. Once again AEM prooved its flexibility <3
