Expression Pedal to MIDI CC issue

[BrufordRules]

Hello,

I have made a simple app to send a MIDI CC from my expression pedal (Roland EV-5) and I have found 2 issues.

• The pedal sends values from 3 to 127 instead of 0 to 127.
• And the worst one. The pedal sends values constantly. Like you were moving the pedal all the time. This cause the DAW to slow down a lot and it's really annoying.

What can I do to stop sending values when the pedal is not moving. And how can I get the whole range of MIDI values.

I have attached a ZIP file with the .flow, and .bin files and a screenshot.

Thank you so much in advance.

Alex

Hello,

Thanks for sharing your questions!

1. You can use the scale node and clip nodes to map the input to a new range or to limit the range of values.
2. You can use some math nodes to get output only when the value changes significantly. You can also use the delay_tick node and float node to change the output rate.

Regarding 2, we consider adding a dedicated node to the built-in collection.

1. scaleノードとclipノードを使うことで、値を新たな範囲にマップしたり、レンジを制限することができます。
2. 変更のあった場合のみ出力を行いたい場合は、数値比較ノードを組み合わせるか、cyclic_tickノードとfloatノードを組み合わせてリサンプリングを行うことができます。

Hi Kai,

First of all, thank you so much for your support.

I have solved the problem of the MIDI range values by extending the R parameter in the exppedalin node to 130 and then subtract 3 to the output value. This way I get 0 at the heel position and 127 at toe position but your solution seems more elegant to me.

About the second issue, I used the _delayms and compare nodes, to compare the actual value with the delayed one and if they match, close a gate to block the output but it didn't work. I don't know what I did wrong.

Hi Kai,

Thank you so much for the suppress node in the last update. It's exactly what I needed.
