PITCH SHIFTING MODES
New
There are 5 different Pitch Modes available for the Looper Engine, these can be found in:
MENU > OPTIONS > LOOP PITCH MODE
1. Samplerate:
Uses a simpler sample rate change approach to change the pitch, in this mode the loop length is also affected by
the pitch.
2. Pitch Shifting:
This mode only changes Pitch without changing the loop length
3. Time Stretching
This mode only changes the loop length without changing the pitch
4. Pitch/Time:
This mode changes both the Pitch and Loop length, similar to the Samplerate option but using the Pitch Shifting/-
Time Stretching methods.
5. Pitch and Time:
This mode separatelly changes both the Pitch and Loop length.
When this mode is selected the [LOOP PITCH] controls the pitch and [REC DELAY DEV.] controls the time stretching.
The Rec Delay Deviation function becomes innactive but the [REC DELAY] is still active.
---
All modes above except the Samplerate use a buffer to make it’s operations, the user can also define the size of
the buffer, diferent sizes have different algorithm “flavours”, these can be found in:
MENU > OPTIONS > PITCH BUFFER SIZE
---
The Granular Engine can be set to the first 3 Modes although mode 2 and 3 will greatly reduce the maximum
ammount of Grains Active possible.
