BTDSys PeerState

What is it?

PeerState allows "snapshots" of the parameter states of machines to be captured and restored easily. You can switch between up to 128 stored parameter values for several machines at once, with only a couple of clicks, one entry in the pattern editor, or one press of a MIDI key.

Installation

Unzip into your Buzz\Gear\Generators\ folder. Add to index.txt if you want, or download an up-to-date index.txt if you're lazy.

Quick-start guide

• Add PeerState to your song, along with some other machines
• You don't need to connect anything to PeerState in the machine view
• Right click PeerState, and select Machines/Parameters
• In this dialog, place checks next to the machines and parameters you want to control
• Click OK
• Double click PeerState, and play around with the resulting dialog

Version history

• v1.0: First public release.

Parameters

• Snapshot - Choose the current snapshot number.
• Inertia - Sets the glide time when changing snapshots.

Attributes

• MIDI channel - Sets which MIDI channel PeerState will respond to.
• MIDI note for taking snapshots - A press of the selected note will cause the current snapshot to be overwritten with current parameter values.
• Inertia update freq - Sets the resolution with which inertia takes place. Lower values give smoother glides, but result in higher CPU load.

MIDI

The MIDI support in PeerState works as follows:

• When a MIDI note is pressed, the corresponding numbered snapshot is restored and set as current. For example, a press on "Middle C" will call up snapshot number 60.
• In addition, a note may be chosen (in the attributes) to act instead as a "store snapshot" key.

Dialogs

There are three dialogs in PeerState, all of which are fairly self-explanatory. But I'll explain them anyway.

Machines/parameters dialog

Here you can choose which parameters you want to include in snapshots. Note that the checkboxes next to machine names indicate at-a-glance whether any of that parameters of that machine are selected.

'Simple' GUI

This is the dialog brought up by a double-click on the machine. You can use the combo box to call up snapshots, and the big button to store current parameter states. An asterisk next to the snapshot in the combo box indicates there is a snapshot currently stored in that slot.

'A/B' GUI

This is similar to the 'Simple' GUI, but more suited for quickly comparing and tweaking several snapshots. The big 'Take snapshot' button is replaced with two arrow buttons for selecting snapshots. And whenever you choose a new snapshot number, the old one is automatically overwritten with current parameter values before the new one is restored.

Thanks

Thanks to Ronny Pries for the initial idea. Also thanks to mute, thOke, XionD, Lee_dC and everyone else who contributed feedback.
