Audacity 2.4.2 and Blackstar ID CORE 20

Also, did you read this part on pager 18 of the ID Core Handbook:

USB Recording Level – Tap + Gain
As stated in the USB Audio section (see page 15), the output level of the USB audio
signal from your ID:Core amplifier can be controlled independently of your amplifier’s
speaker volume by holding down the Tap switch (11) whilst turning the Gain control
(3) on the front panel.

I hope this helps. :smiley:
