Applying a pitch-envelope while 1 is already used for filter

Post by SlimPhatFrank » Mon Jul 25, 2011 10:49 am

Like the topic tells - is that possible on a SlimPhatty?
To make it simple: Thank you, Bob!

It is possible in a tricky way w/ the new firmware.

If you set up the LFO to retrigger w/ a keypress, set it to a triangle, saw or ramp wave and a really slow Rate. It can be a pseudo-Envelope Generator to modulate the pitch, filter, osc. 2 or wave

Details are in the user notes I believe.

Hope that helps

You can use the method above or you can use the filt ENV source in the LFO section. With that source the pitch ENV is the same shape as the filter ENV.

The amp ENV can only be used for modulating the VCA. It is always positive (goes up then down).

To modulated pitch with the filter ENV, set LFO source to Filter ENV and destination to pitch. Turn LFO Amount all the way up and use the mod wheel to set the amount you want the pitch to change.

There are 2 ways to have the Filter ENV affect the cutoff. The 1st is to use the modulation section in the same way as pitch but set the destination to filter (if already using it for pitch you can go into the advance preset menu scroll down to 2nd mod dest and set that to filter). Also, when 1st using the mod section to apply the ENV to the filter turn the EG Amt in the filter section to 12 O'clock (no ENV is directly applied). Depending on what you want this method of filter modulation may be desired. The amount of envelope applied to the filter and pitch will be the same, controlled by the mod wheel, and always positive.

The 2nd way to have the Filter ENV modulate the cutoff is with the EG Amt in the filter section. Turning clockwise from 12 O'clock will be the same as increasing the mod wheel (with the 1st method), positive ENV is applied with the amount of change in the cutoff increasing the further the knob is turned. With this method the amount of ENV applied to the pitch and filter can be independent (if filter is not chosen as a destination in the LFO section). Turning counter-clockwise from 12 O'clock will apply a negative ENV to the filter. A negative ENV will decrease then increase the cutoff frequency. The further counter-clockwise from twelve O'clock the more the cutoff frequency of the filter will be changed. EG Amt has no effect on how the ENV behaves in the LFO section. The amount of the ENV affects the filter cutoff from the mod section and the EG Amt are additive. If EG Amt is set negative and filter ENV is the source in the LFO section with destination 1 or 2 set to filter, you can cancel out the modulation to the filter cutoff by increasing the mod wheel.
