Mixer
You can copy Programs from one channel to another using drag-and-drop, or by
using the Edit menu cut, copy, and paste commands.
You can delete a Program from a channel by using the Edit menu cut command, or
by pressing the Delete key.
In Type (Input Type)
Program, Audio In, Stream, Off. This selects whether the channel's input will be a
Program, an Audio Input, or a Stream. The Input Type controls the available
settings for the Input Slot, as described above.
Off means that the channel is unused.
Mono/Stereo Indicator
The input to a channel can be either mono or stereo. For instance, Programs can
have stereo or mono outputs, depending upon the Patches which they use; the
user can also select mono or stereo audio inputs.
Stereo inputs use two input busses, while mono inputs use only one. The
mono/stereo display is intended to help the user to manage bus resources by
making the mono/stereo state explicit.
MIDI (MIDI Channel)
A1-A16, B1-B16, Off. This is the MIDI channel used to control the mixer channel,
including the mixer parameters (volume, pan, sends), the Program, and the Insert
Effects. There are two sets of MIDI inputs, labeled A and B, with 16 channels each.
When using OMS or FreeMIDI, these correspond to the OASYS PCI A and OASYS
PCI B devices, respectively. When using the built-in serial drivers, only the 16 "A"
channels are used.
If you like, you can also disable MIDI control for the mixer channel by selecting
"Off."
You can layer Programs by setting two or more mixer channels to the same MIDI
channel.
Level Meter
The meter shows the stereo output volume of the channel, post-effects.
To monitor the input to the channel, double-click the Volume fader to set it to 111
(0dB), and bypass all of the Effects by clicking on the numbers to the left of the
Effects slots. (For more information, see "Bypassing Effects" on page 27.)
Clip Indicators
The topmost, red lights are clip indicators for the left and right channel outputs. To
clear a channel's clip indicators, click on them. To clear all clip indicators on the
Mixer, option-click (MacOS) or CTRL-click (Windows) on any clip indicator.
