Hi there,
while I agree with you that for the marketing point of view it would be better to mantain the midi-in standards, I disagree that standard midi is good enough for analogue controlls.
I just want to explain why at the moment PedalPro does not have midi-in software compatibilty.
When I started designing the PedalPro, it was to be used with MIDI-IN. This is why the physical compatibility.
During the development I realize that controlling the PedalPro with an external controller was to much programming and not really efficient.
But the point when I decide that I had to abandon the MIDI-IN was the wah effect.
For me making a great wah was essential. As you all experienced guitar players, you know that wah is really an important effect.
Now if you look in to the market, there are many multi-effects MIDI-IN compatible.
But none of them can make a great wah sound better or comparable to a Crybaby (or other models).
There are few reasons for it:
- All the Wah in a multi effect are digital
- Midi messages are not for free. Every time you send a midi message you send 3 bytes out. If you are using RPN you need to address 6 bytes for one position of the expression pedal.
Every MIDI byte is 0,320 ms. This means that for RPN message I need almost 2 ms !!!
If you want to have a very good wah that it react as fast as Wah pedal you need to have your latency less then 1ms.
If you control two formant filters to make a vowel you will need 4ms (2x2 ms).
- Zipper noise. see

the work around is to use a damping factor which also introduce a latency.
- Using midi with 7 bit resolution= 128 levels is really bad for most analogue parameters. So it is not an option.
Of course I understand, that changing a standard to go for a proprietary protocol means looking for trouble, but I had to make the decision based on improvements and achieving better sound quality.
MIDI-IN compatibility would require a new software to be uploaded in the PedalPro via USB
But the magic and the beauty of our controlls will be drastically reduced in order to compromise with the MIDI protocol limitation. And then a lot of programming for the users.
The ADES protocol is bidirectional, does not require programming, and takes care about the dynamic difference between each analogue parameter.
Further you do not need to re-program the names in both foot-controller and effect unit.
After all what we really want is to enjoying the play and having a great sound.
Just one last question..
How many presets of your set up use different expression parameters with the same expression pedal ?
Who much takes for you to programm one sound where the expression is a wah, one where the same expression is a tremolo depth and one where the same expression is a volume pedal and they all have distinguished ranges ?
Well with PedalPro this takes less then 20 sec.
