To upload impulses, connect the CabZone X to your PC (the USB A (m) — micro-USB cable isn't included in the package). After that, the device will be identified as a drive, allowing for impulse upload.
When the microSD card is used for the first time, an AFX folder with stock impulse files is automatically created on it. The files are stored in subfolders corresponding to the CAB knob positions. To use custom impulses, replace the stock files with your own.
Impulse format: mono 24bit 48kHz WAVE PCM1, uncompressed. The device uses the first 1000 samples of the impulse (about 20ms). If you upload a longer impulse, the CabZone X won't process any data beyond the 1000 samples. The first thousand contains all the crucial data on the cab's own initial reflections. Longer impulses also include reflections and frequency distortion introduced by the room where the impulse was recorded.
When the CabZone X is connected via USB, the LED turns blue. The cabsim's audio functions are still accessible. If you haven't copied any new impulses to folders in the device's memory, no changes happen to its operation. If you have copied a new impulse to the folder corresponding to the current position of the CAB knob, turn the knob to another position and go back to the previously selected one. After that, the new file will be uploaded to the device's memory.
To re-record the stock impulse files to the built-in memory, delete all folders from the drive. This will cause the device to automatically create the AFX folder and all its contents.
When done using the device, eject the drive safely and disconnect the USB cable.
Alternative firmware (patch) upload is currently in testing. The function is already available in CabZone LE (to support page). The detailed description for the CabZone X will appear later.
