Sound Parameters – Mixer75 Waldorf Q User’s Manual. If you turn the pitch of one oscillator down very far, you can get a very similar effect toAmplitude modulation. Use this for sounds with a periodic element if you like.RingMod BalanceF1 64…mid…F2 63Determines the ratio of the ring modulator’s signal that is sent to the inputs of Filter 1 and Filter 2 (seerouting picture). If set toF1 64, the signal is sent to Filter 1 only. Higher values will increase theamount of signal that feeds Filter 2 and decrease the amount of signal that feeds Filter 1. If set tomid,both filters will receive the same signal level. If set toF2 63, the signal is sent to Filter 2 only.Noise / Ext.0…127Volume of the noise generator respectively the external sound source connected to the stereoExternal In C jack. This control behaves differently depending on the setting of N/E Select F1/F2feed in the Mixer Edit menu. Noise is a fundamental source for any kind of analog-type percussion.Also, wind and other sound effects can be created by using the noise generator. Please note that ifyou use an external sound source, you still have to trigger the Q’s envelopes to get the signal passedthrough. So you have to generate MIDI notes by the keyboard, a connected sequencer or the internalstep sequencer or arpeggiator to hear the audio signal.Noise / Ext. BalanceF1 64…mid…F2 64Determines how loud the signals set up in N/E Select F1/F2 feed are sent to the inputs of Filter 1and Filter 2. Noise / Ext. Balance behaves differently than the other Balance controls. It doesn’t movethe signal between Filter 1 and Filter 2 but controls the loudness ratio between the two signals set upin N/E Select F1/F2 feed. The signal set up in F1 feed is always sent to Filter 1 while the signal setup in F2 feed is always sent to Filter 2.Mixer Edit MenuThe following parameters can be accessed via the display menu.

F1 Feedis always routed to Filter 1 while F2 Feed is always routed to Filter 2.
