Hello,
We often use parameters to tune instrument/effect gain and/or EQ frequency via the parent event (or an external editor that drives the parameter values). However, due to parameters being linear in nature, there isn’t an easy way to 1:1 map the logarithmic gain or frequency controls to the corresponding linear parameter values, outside of creating a lot of automation points or getting it “close enough” by shaping the curve a bit.
Example: Volume and “Gain” parameter both scale from -80 to +10, but due to one being linear and one being logarithmic, they don’t align (-40 = -18.9):
Internally we’ve built a linear gain plug-in to get around this, but having to instantiate extra DSP purely to map values isn’t ideal.
What I would love to see as new parameter types are “Logarithmic Gain” and “Logarithmic Frequency.” By choosing “Logarithmic Gain” the parameter would scale from -80 to +10 logarithmically which would match 1:1 with instrument and effect gain. Same for frequency, the parameter would scale from 20Hz-22kHz and scale logarithmically like the EQ effects do.
Conversely, (and now that I’m typing this, maybe it’s the more logical approach) it might be easier to be able to right click a gain or frequency control and select whether it functions linearly or logarithmically, negating the need for logarithmic parameter types.
Either way it would be an amazing addition to the FMOD toolset!
Thanks for your time,
Todd
