<p class="MsoNormal">It was just a matter of time before MIDI jumped on the BLE bandwagon. I’ve read the spec. I think it guarantees accurate rendering by timestamping the data but it doesn’t fix the problem of latency (in other words, it’s not real time,
therefore it’s poor for live performance).<o:p></o:p></p>

<p class="MsoNormal">Hey Quincas,<br>
<br>
MIDI is not limited to 128 steps!<br>
<br>
Pitch Bend always has 16384 steps, and there are 32 Continuous Controllers with both MSB and LSB for 16384 steps. Mod Wheel is one of those 32 CC numbers. Across all 16 channels, that makes a total of 528 controls on a single MIDI cable that each have 16384
steps. This is all standard MIDI 1.0 specification.<br>
<br>
I'm not familiar with MIDI over Bluetooth with regard to latency or any limitations in resolution that might be specific to Bluetooth, but I don't see how MIDI resolution could be any different over Bluetooth than any other medium.<br>
