Parat+ Fader Edit View – basics
Each Parat+ Fader can be fully customised. This includes the basic OSC and MIDI settings which are available in the App for each fader.
- OSC address
- Parameter range sent over OSC
- MIDI channel and controller number
Open the Edit View by either tap on the first menu tab.
Or double tapping onto the centre of the Option Wheel.
Scroll up and down to access all the available settings.
It is possible to resize the Edit View with a pinch gesture.
OSC address (transmitting):
Edit the OSC address you want to use. Parat+ enables editing all OSC addresses in the app, as some OSC enabled software have fixed OSC addresses for its parameters.
For example when working with Reaper, the value fader of Track 1 can be adjusted with the OSC address /tracks/1/value and the panning with /tracks/1/panning.
MIDI controller number and channel:
Scroll down to access and edit the MIDI controller number and channel.
Parameter range sent over OSC:
Define the number range transmitted via OSC. Software and hardware developers might have implemented a standardised value range of 0. to 1., however, OSC itself does not limit the user to any range.
For example when controlling the cutoff frequency of a high pass filter, it might be preferable to use a parameter range of 150 to 5000 to reflect the actual values. Please note to ensure what limitations the receiving software might have.
‘<<‘ resets the range to the default linear range of 0. to 1..
OSC data type.
By default a fader is setup to send floating point numbers. Because some Software and Hardware might be limited to receive and process whole numbers (integers) only, the data type for the OSC transmission can be controlled.
Please note that changing the data type to integers will most likely require the parameter minimum and maximum to be adjusted to a higher range than 0 to 1, as otherwise the fader will only produce these two numbers 0 and 1!
Fader Range Minimum, Maximum and Curve:
In certain situations it might be preferable to set the Range Minimum, Maximum and Curve manually rather through the multi-touch gestures.
Use the ‘<<‘ to reset the range to the default range of 0. to 1. with linear distribution (0.5).
OSC transmission of value and range:
Parat+ can be set to limit transmission of the scaled Fader Value only (‘OSC value only’) or add the Range Minimum and Maximum (‘OSC transmit all’). In either case the transmission is as individual messages in following format:
The transmitted value is calculated in relation to the minimum, maximum and curve and scaled according to the defined Parameter Range.
The transmitted value is the fader minimum.
The transmitted value is the fader maximum.
Transmitting the Range Minimum and Maximum, as well as the actual value (‘OSC transmit all’) enables to use all available streams to be used for custom processing in suitable software (e.g. Max7, Max4Live, PD etc.).
Parat+ Fader Edit View – further settings:
Further customisations allow more complex setups and integration of Parat+ into performance and production systems.
Value controlled by (OSC address):
When Parat+ receives OSC data streams it automatically creates Source Faders for each OSC address received. When entering the OSC address in the ‘Value controlled by (OSC address)’ the data of the respective Source Fader is used to control the Fader.
If you enter an OSC address which is not found in the available Input Faders, it will be created automatically on the assumption that this was done to prepare Parat+ to receive this OSC address.
PLEASE NOTE: Currently there is no limit of the amount of Source Faders in Parat+. However you might want to make sure that you keep an eye on how many streams Parat+ receives to ensure that the internal means to deal with the connections of the streams remains manageable.
Input Calibration (minimum and maximum):
The minimum and maximum value for the Input Calibration can be set manually in the edit Edit View or by activating the calibration mode in the Option Wheel. The incoming values from a Source fader enables are calibrated and modified to set the controlled fader to react only to a portion of the Source range. The incoming values are normalised according to the minimum and maximum values of the calibrator. The fader is at 0 when the incoming Source values are smaller or equal the calibration minimum and the fader top (1) will be reached when the incoming source values reach the calibration maximum.
E.g. When the fader is controlled by the source /quaternion/x, which report the tilt of your iOS device on the x-axis. The minimum of the calibration mode can be used to set a convenient angles of the device to have the controlled fader at its lowest value and highest value.
Minimum controlled by Source (OSC address):
When Parat+ receives OSC data streams it automatically creates Source Faders for each OSC address received. When entering the OSC address in the ‘Minimum controlled by Source (OSC address)’ the data of the respective Source Fader is used to control the Range Minimum.
Maximum controlled by Source (OSC address):
When Parat+ receives OSC data streams it automatically creates Source Faders for each OSC address received. When entering the OSC address in the ‘Maximum controlled by Source (OSC address)’ the data of the respective Source Fader is used to control the Range Maximum.
