I notice when using the arp on my Keystep Pro that the first note is almost always played twice.
For example...
If I hold down a C and D I will get D,D,C. After that it behaves normally while holding down those keys
If I hold down an Fminor (F,G#,C) I will get G#,G#,C,F. After that it behaves normally while holding down those keys
This issue repeats if I play a different set of notes.
My firmware version is 2.0.1 build 989.

I wanted to add something to this after a bit more research.
1. This doesn't seem to happen as frequently when the arp mode is set to "order".
2. It is more difficult to tell if it is happening in "random" mode.
Here is some data from Midi-Ox:
The arp mode was set to Up, tempo at 30 BPM, and time division 1/4.
I pressed all keys in the C major chord at the same time.

I tried the same with a C minor chord.

Similar behavior is seen when the arp is set to chord mode and playing a C major chord.
First it plays a C note alone and then it plays the chord.
