NOTE: We are now only recommending Imprint setups in Ableton Live without the use of Bidule. We will leave this article online as a reference for users have already implemented it. In future, all new setup information will be on the Articles page of the Support section of the website.
In this post we are going to go create a polyphonic Imprint setup in Ableton Live with Massive. This setup is for a 4-string bass.
In order to achieve this setup you will need a multiple input soundcard, Bidule, Reaktor 6, and the IR Imprint Multi Module 4.
The first step is to set up Bidule on its own MIDI track within Live.
In this setup all the synths (one per string) and Reaktor 6, hosting the Imprint module, reside within Bidule.
Now we are going to focus on setting up the Bidule patch. Below is a screenshot of the final result.
NOTE: When we loaded the Reaktor 6 plugin we selected '16 ins 2 outs'.
REMEMBER: In the polyphonic Imprint modes, ie. Imprint 1 and Imprint 2, the bass will be sending on 4 separate MIDI channels, ie. one per string. The MIDI Splitter is designed to remap each channel to MIDI channel 1 so that all of the synths can be set to receive on MIDI channel 1, removing the need to have each synth set to receive on a different MIDI channel.
NOTE: Link the outputs from left to right in the order of synths so Massive [MASTER] is 1 and 2, Massive  is 3 and 4, Massive  is 5 and 6, and Massive  is 7 and 8.
Now you have the Bidule patch ready to go!
Now we are going to set up the MIDI tracks.
NOTE: By grouping the tracks in this way we can expand and collapse multiple tracks with the click of a button.
Now we are going to set up audio tracks for the piezo signals from the FSI-1 piezo outputs.
NOTE: This setup assumes that the piezo signals from the FSI-1 outputs are being routed to the input on the audio interface with the same number. So, for the 4-string we use piezo outputs 1-4 with piezo output 1 (G) going to input 1 on the audio interface, piezo output 2 (D) going to input 2 on the interface, and so on.
NOTE: In this post we don't attempt to include the bass audio from the magnetic pickups since it is not required to implement a polyphonic Imprint setup. To do this you will need to create a separate audio track and route the signal accordingly.
The MIDI SEND mode on the bass needs to be set to either Imprint 2 or Imprint 3 for polyphonic Imprint setups.
Unfortunately, with some synths parameter linking is not completely comprehensive. This is the case with Massive. As a general rule you will find that most parameters that are controlled by a knob or a slider will be linkable while controls that use switches, buttons or select lists are not accessible.
Also to change patches across multiple instances of Massive from the MASTER plugin requires loading patches into the Programs List which can be found under the Browser view.
NOTE: We will write up instructions on the specifics of this appraoch to patch changes in a separate post.
