If you experience this issue please read this thread for the many ideas on how to work around the noise. Here is a summary (try these in this order):
- Make sure the audio volume is high, ideally maximum (on the Midronome but also on your other devices) to get the best signal-to-noise ratio
- Use TRS cables in your setup, in particular on the Midronome Audio output (set the switch to "speaker" = Balanced Line Out)
- Power the Midronome from a USB wall plug / USB charger - if needed use a splitter USB cable like the one coming with the Arturia Keystep
- Use a hum eliminator / USB isolator on the USB power supply

Short description of the issue:
When the Midronome is connected via USB to the computer, there is a very loud hum in the audio output when connected via an unbalanced (TS) audio cable. It's so loud I would consider it unusable to use as a click track.
Setup (devices connected to the Midronome and how):
PC > USB Cable > Midronome
Midronome > Unbalanced Audio cable (TS) > Mixer input
I've tried multiple USB and audio cables, and multiple USB-ports, with or without (powered) USB-hub.
Steps to Reproduce:
Connect as described above and listen.
In the following cases I have no noise:
- When connecting the Midronome with a TRS-cable straight into the mixer.
- When listening to the audio output via headphones.
- When powering the unit with a separate USB-charger, without connection to the computer, there is also no noise, even when using an unbalanced audio connection.
Expected Behavior:
I'd love to only hear the click track, no noise (or way less).
I can accept that I have a suboptimal setup, with most of the cables being unbalanced, but midronome is the first device that really gave me troubles with that.
Actual Behavior:
I made a recording:

Note:
The noise varies slightly in volume and timbre depending on what is shown in the LED-display: the more segments are lit, the louder the noise becomes (the audio recording starts at 71 BPM, which has only 5 segments in the display, and ends at 128, which has 15 segments).
Playing with the brightness setting also gives you a nice change in timbre.
The volume of the click is 5/4 in the recording.

Has the Midronome firmware been recently upgraded, from which version to which version?
I upgraded to the 1.0 firmware when I received the unit.
