Dynamics control in Dorico

[PaoloT]

Hi,

Dorico can use expression maps to decide which MIDI message will control dynamics in the VSL instruments.

There are up to two dynamic control messages for each entry of an expression map: a primary and a secondary one. According to the documentation and the discussion I have followed, this was mainly conceived for those libraries where you send an initial value via Velocity, then change it with Modulation (usually CC1).

Other cases are possible. The expression maps developed by VSL for the SYzdSE libraries include both the primary (Velocity) and secondary (CC2) dynamic control. I wonder if this is done so that you can load either the Velocity-controlled presets, or the VelXF ones, and Dorico can control the one or the other, due to both dynamic control streams are included in the expression maps.

Hello Paolo!

The SYNCHRON-ized Special Edition presets have Velocity XFade disabled by default. You can leave the presets this way or you can enable Velocity XFade to enable dynamic transitions within single notes. It's also possible to turn Velocity XFade on and off during a project with CC28 commands. Whatever way you choose, the SYNCHRON-ized Special Edition Epxression Maps are prepared for it, because velocity and CC2 commands are defined for dynamics in the Expression Maps.

Best regards,
Andi

Andi, thank you for your answer!

So, Dorico doesn't make any priority between the two streams of Dynamics control. The one and the other can be used at the same time. With VSL libraries, which one will be considered will be decided by the CC28 control, or the switch in the patches.

This is particularly great for the "XF sus" versions of the Synchron Strings Pro presets!
