I can’t seem to find relevant information for creating multi-velocity drum kits in Polyphone. I need some help with the following:

How to set polyphony, one-shot, and choke group.

Thanks in advance, love the program.

PS There seems to be many places to set the same parameters- pan, velocity, attenuation, etc; is there a hierarchy? The values don’t seem to migrate.

Hello AmpApps.net,

Welcome to the world of SoundFonts and Polyphone!

I'm not sure what you mean by polyphony, but you can set the drums to one shot by setting the loop playback to the first option (which looks like a white arrow with a gray handle sticking out of it).

I'm also not sure what a 'choke group' is, but I'm assuming that it's the effect of the open hi hat sound cancelling when you press the pedal hi hat or the closed hi hat. In this case, set all of the hi hat's 'exclusive class' to 1 to create this effect.

The values don't seem to 'migrate' because you can set them manually for the instrument and preset. Don't forget to not go past 65536 parameters!

Thanks,

Thanks for the great quick response!

Re: polyphony- In a drum sample-set repeated strikes at the same or different velocities on the same drum instrument (snare etc) should not stop the previous strike (trigger) sample playback. Real drums do not cease vibrating instantly when another strike occurs, neither shell drums nor cymbals. Customarily sample builders allow a setting for how many instances of a sample file can be active at one time...polyphony.

A choke group is as you said, in the case of a drum kit the one place where a cessation of the sound is normal is in stopping a hi hat wit( the foot pedal. A closed, and pedal, trigger should stop an open hi hat sample.

Do you know if round robin or random sample rotation is possible as well? A drum kit sample set can sometimes include left and right hand samples at each velocity layer. These would be cycled in a round robbin format mimicking a two handed player.

I have looked at a couple other drum kits and I suspect some sets use a slow modulation to fake this.

Thank you again, I am hoping to create my personal transportable drum kit.

Hello AmpApps.net,

Thanks for replying to my message.

I now get what you mean by 'polyphony'. If you want the sound to keep on going after you release the key, set the release time to 100 seconds on global. Without this, when you release the key, the sample will abruptly stop playing. If you set the release time to 100 seconds, the sound will not abruptly stop playing, and you will get a realistic sounding drum sound.

Round robin and/or random sample rotation is not possible due to SoundFont limitations. Unfortunately, version 2.04 is extremely limited in what it can do. Maybe we ought to come up with a new standard with everything we want.

Thanks,

Strix.

Do not place the release time in the preset screen; place it in the instrument screen.
