Sound Parameters – Xphorm – Interpolating between two soundsWaldorf Q User’s Manual 62Xphorm – Interpolating between two soundsThe Xphorm function gives you an easy and powerful way to interpolate between two differentsounds. Interpolation means that all continuous sound parameters of two sounds are changed by acertain ratio determined by the Xphorm source.Sounds difficult? Here’s an example: imagine two sounds with different settings for Filter 1 and theAmp Envelope. When you move the Xphorm source, i.e., the Modwheel half up, the parameter valuesare in the exact middle of the two sounds. The following table shows some parameters of the originalsound, the interpolated sound and the sound setup in the Xphorm menu:Original Sound 50% Interpolated Sound Sound set up in the Xphorm menuCutoff 32 64 96Resonance 0 5 10Env. Amount +60 +15 -30Attack 8 7 6Decay 25 45 65Sustain 0 32 64Release 20 30 40Table 9: An example of two sounds that are XphormedYou can easily see how the parameters are changed. I.e., Cutoff was set to 32 in the original soundand to 96 in the Xphorm sound, so the 50% interpolation is in the middle: 64. The same is true forbipolar parameters like Env. Amount. You also see that Xphorm is a blending of parameters, not afade out and fade in of two different sounds.Xphorm can change all continuous parameters, but no switch parameters. So, the basic functionalityis similar to what would happen when you would set up a lot of modulations in the variousmodulation slots. But Xphorm is faster and easier to set up and sometimes it creates surprising resultsyou wouldn’t have found by manually setting up modulations.Continuous parameters include:• LFO Speed, Delay, Fade• Osc Pitch, PW, Glide and Mod Amounts• Mixer Levels and Balances• Filter Routing• Filter Cutoff, Resonance, Drive, Pan and Mod Amounts• Amp Volume and Mod Amounts• Envelope Rates and LevelsThe Mod Matrix Amounts aren't xphormed because it is very likely that the sources and destinationsare different in the xphormed patch.Switch parameters that aren't xphormed:• LFO Shapes, Sync, Clocked• Osc Shapes, Sync and Mod Sources• Mixer Input settings for N/E• Filter Types and Mod Sources
