* to limit the pulsewidth from 5% to 95% (hardware is full range)
* to remove DC from the pulse waveform output (hardware contains DC for non-50% duty cycles)

* MotionMTR optionally doesn't use the 10V normalling on inputs if in audio mode to avoid acidentally adding unwanted DC to audio signals, see context menu. E.g. if you temporarily unpatch an audio source whilst using it it mixer mode, you get 10V DC suddenly and a nasty pop.

* Burst hardware version version can also set the tempo by tapping the encoder, this is not possible in the VCV version.

---------------------------------------
MISO is an architectural lettering font
completed in 2006 by Mårten Nettelbladt.
---------------------------------------
MISO is available in three weights
(Light, Regular, Bold)
in TrueType and OpenType format.
---------------------------------------

L I C E N S E I N F O R M A T I O N
---------------------------------------
MISO is a free typeface. However,
there is one important limitation:

MISO MUST ALWAYS REMAIN COMPLETELY FREE

You can use MISO for personal and commercial work.
You can share MISO with your friends
as long as you include this text file.

You must not sell MISO.
You must not charge someone else for using MISO.
You must not bundle MISO with a sold product.

Use it, share it, but keep it free.
