Not sure why sending MIDI CC messages would cause notes to ‘lock up’. You can stop CC messages from being sent from the Organelle if you edit the mother.pd file. From the manual: > #### The **mother.pd** Helper Patch > > **mother.pd** exists at the root (or top) directory of the Organelle, which is located on the microSD that comes preloaded within the Organelle hardware. This helper patch is the other half of the data handshake between the Pure Data patches we run and the Organelle’s hardware. > > In short, this helper patch is executing the raw communications with the Organelle hardware. (This is done using the _Open Sound Control_ [_OSC_] protocol.) > > Accordingly, **mother.pd** is necessary for the general operation of the Organelle. That is why this patch is loaded concurrently with any patch that you call up. > > > **NOTE:** In general, you should not edit **mother.pd**. That being said, the Organelle will use any file named **mother.pd** that it finds within the **Patches** folder of your microSD card or USB drive. By copying the root directory’s **mother.pd** to your **Patches** folder, you could experiment with editing this patch while keeping the master version clean. Once you have a copy of the mother.pd file, you can edit it so that the input connections to any [ctlout] objects are severed. This is an older post but the instructions starting at step #5 are relevant: > [@Changing MIDI CC Output](https://forum.critterandguitari.com/t/changing-midi-cc-output/996): > > Follow these steps to change MIDI CC output on the Organelle: Eject the USB drive in your Organelle and place it in a USB port on your computer. Download [PureData](https://puredata.info/downloads) on your computer if you have not already. Download [mother.pd](https://canada1.discourse-cdn.com/flex035/uploads/critterandguitari/original/1X/03ffe4aa85bf33ac86425a44babee49ab105319f.pd). A version of this file is always running on the Organelle and interfaces with every patch. To set your Organelle to send MIDI CC controls of your choosing, a new mother patch must be created to override the built-in mother.pd. Move mother.pd into the patches folder on the … --- _[View the full topic](https://forum.critterandguitari.com/t/midi-out-weirdness/8807)._
