(4.18.5) USB Audio
USB Audio: This setting determines whether or not Flex Prime
is sending a USB audio signal over a USB connection. Tap
On to enable sending of the USB audio signal with the
selected Sample Rate. Tap Off to disable the USB audio
signal. To change the Sample Rate, set USB Audio to Off
first, select the correct sample rate, set USB Audio to On
again, and restart your DAW.
Sample Rate: This setting determines the sample rate of the
USB audio signal: 44.1 kHz, 48.0 kHz, or 96.0 kHz. Remember
to select the same sample rate as the one in your DAW. Also,
set it before opening your DAW.
USB Mode: This setting determines what audio signal Flex Prime sends over the USB connection and how its
outputs function while doing so:
• Live: The audio signal will be sent to your computer as well as to Flex Prime’s outputs.
• DAW: The audio signal will be sent to your computer only. Flex Prime’s outputs will be disabled to prevent
any latency while monitoring.
• Reamp: Your computer will send an audio signal to Flex Prime, which will process it through the current rig
and send it back to your computer. Flex Prime’s outputs will be disabled to prevent any latency while
monitoring. See (4.15.3) USB > Reamping to learn how to configure your DAW for this process.
USB In Level: This setting determines the incoming USB Audio level, from -60.0 dB to 12.0 dB.
(4.18.6) MIDI
These settings determine how Flex Prime sends and receives
MIDI information to and from external devices. These settings
affect only Flex Prime’s MIDI Input and MIDI Output.
MIDI Thru: Tap On to use the MIDI Output as a MIDI
throughput; any MIDI information sent to Flex Prime’s
MIDI Input will be sent directly to the MIDI Output. Tap
Off to use Flex Prime’s MIDI output normally; Flex Prime
will be able to send its own MIDI information out of the
MIDI output.
Receive MIDI Clock: Tap On to enable Flex Prime to receive
MIDI clock information. Tap Off to use Flex Prime’s own
internal MIDI clock (which will not be sent out).
Prog Change: Tap Send to enable or disable Flex Prime’s transmission of MIDI program change messages
when you press the upper-left (Rig ) or lower-left (Rig ) switch. Tap Recv to enable or disable Flex Prime’s
reception of MIDI program change messages from an external MIDI device.
MIDI Channel: This setting determines the MIDI channel(s) from which Flex Prime will send and receive MIDI
messages. Tap this field, turn the encoder to select all channels (Omni), or 1–16, and then press the encoder.
