ANSELMI from the Elektron-Users forum discovered this little trick using the Elektron Analog 4. A great use of the CV track if you aren't using it on any external devices.

"This kick is generated by using the LFOs of the CV track as well as one CV output

You know, LFOs can go fast and since they got sine wave and you can make it reset at each trigger you can get a solid boomy kick out of them.

Just go to LFO1, set it at a speed that you can hear, then choose CV value as destination and then use the second LFO to modulate LFO1´s speed (pitch) with an expo decaying wave in "one" mode

then you can use ENV2 to shape the amplitude of your kick...or just the fade out parameter of LFO1 (much less accurate though) or a combination

of course it´s not for kicks only, you can make a lot of stuff with the LFO1´s waves...metallic FM tones, lo-fi noise stuff, sine bass, you name it

although LFO1 is fast enough to actually be heard it doesn´t have the quality of the proper oscillators, and it´s digital, not analog

anyway with some tweaking and p-locks you can get another track of sound just sacrificing one CV channel

and if you don´t want to mix it externally just plug it again into one of the audio inputs!"
