Osi-Op : Making a Kick Drum (Drum Synthesis) : Vaemi (Eurorack)

"Hello
Today we will make kick with Osi-Op and talk about drum synthesis.
First, let's set up our audio signal chain.
Now we connect the output of our Main VCA to our speakers.
We plug the Sine Wave Output of Oscillator 1 to channel 1 of VCA.
Gozinta is a preamp module. We will use this module for clipping later in the video.
We connect the trigger from the sequencer to the Trig Input of the Function Generator.
With the help of Stack Cable, we will route this trigger signal to Trig Inputs of other function generators.
That is, Trig In 1 will directed to Trig In 2, Trig In 2 to Trig In 3 and Trig In 3 to Trig In 4.
For clipping, let this cable stay here for now.
The first Envelope will control the amp.
the second Envelope will be connected to the LPG module which will control the FM signal.
LPG Output will be connected to the TZ FM Input of the 1st oscillator.
Now let's connect your 2nd oscillator, which will make FM, to LPG.
One of the most important connections that will now create the kick and drum synthesis is that the Envelope controls the frequency of the Oscillator.
For this, I multiply the output of 3 Function Generators with a multiple and direct them to 2 oscillators.
I usually prefer to use 2 Envelopes to control the frequency of the oscillator.
Let's use this envelope by duplicating it over buffered multiple.
the fourth envelope will set it shorter to get a sharper, brighter, punchy attack sound.
I connected the third envelope to the Exp.FM input and the fourth envelope to the 1v/oct input.
After all, they are doing the same thing on both entries. At this point, some minor changes can be made.
Now we can start to hear the patch we made.
After all, you can kick with a single envelope generator, but using too many envelopes this way will give you a lot of flexibility and freedom in making sounds.
Since the Thru Zero Fm technique does not distort the frequency of the oscillator, it will allow you to shape your kick's first attack sound on a much wider scale.
Now let's activate clipping.
In this way, you can get sounds with richer harmonics, harder, brighter, and the low end is more stable. In this way, you have a chance to get much more aggressive sounds."
