The first time you start Temper it will take you through the basic setup, which involves selecting an audio interface and one or more VST paths (both selections can be changed at any time by choosing Setup->VST and Audio from the main menu).
During setup, Temper will create a folder in C:\Documents and Settings\(your account)\My Documents\ (Also available from the Windows Start menu under My Documents). There will be an Angry Red Planet folder containing the Temper folder and its various data. This is the only place Temper stores information on your computer.
To uninstall, either manually delete the Angry Red Planet folder created during the install or run the TemperUninstaller located in the Temper download, then delete the Temper download.
The settings available from Setup->Appearance allow you to customize the application look. From here you can either select a skin (see skins/example-readme.txt in the Temper download folder for a description of skinning) or set padding on buttons, if you want the controls to be larger. Both of these settings require you to restart the application.
The FX Background preference lets you select a shape used to shade the FX in the pipeline view, in case you're not so down with the flat look. The shape is applied by generating values along the X and Y axes and blending them together. If the shape contains a single shape, then it is used for both the X and Y, otherwise the first shape is used for the X, the second for the Y. All positive values will tint the FX, while negative values will tone it.
Most shapes don't make much sense as visuals, so Temper inclues a folder in the shapes button called Visual, with shapes designed specifically for this purpose.
The settings available from Setup->Behaviour allow you to customize the application behaviour.
Invert song position grid. Temper uses the convention of forcing time-based operations to quantize to the current grid, and holding down ALT to defeat the grid. By default, the song view uses a measure-based grid, but this can be annoying for the song position, so this setting switches that behaviour: By default, the song position uses no grid, but holding down ALT will apply the grid.
Invert end time quantize. This setting affects notes in the piano roll: By default, the Wand tool (used to resize notes) ignores the time grid, and ALT is used to engage it. This setting reverses that behaviour.
Alter performance time when ALT is held. (Only available if you have a license) When this setting is on, holding down ALT while editing notes in the piano roll will change the note's performance time, not the display time. This is a natural partner to disabling the time grid: It's a way to rapidly introduce subtle variations in timing.
New controllers have flat ramp. This is a global switch to force all newly created controller events to have flat ramps.
The general settings are available at any time from Setup->General.
Open previous songs. When selected, Temper will open up on any songs that were previously opened when last used.
New song template. When selected, songs created with File->New will use the template instead of the default empty song.
Track scrolls with playback. When selected, any track opened in the browser will scroll to the current song position as the song is playing.
Track plays to end of song. When selected, pressing Play in the track editor will continue until the song is then stopped (by default, tracks stop playing at the edge of the view).
Undo history. Number of edits to retain for undo.
Author. When creating new objects (such as shapes) the author name is used to maintain unique keys across all Temper users.
The first time you run Temper, it will ask for your ASIO device. If your audio interface does not have ASIO drivers, try installing the freeware ASIO4ALL application and restarting the Temper setup. If you do not have a valid audio interface, you can only use Temper as a MIDI sequencer, and you're done with the setup procedure.
If your audio interface is supported, you will be given the option of adding one or more VST search paths. There are a couple things to note: Temper will create a structure to mimic your folder layout, and Temper will scan shortcuts in the VST folders. This means you can create a completely custom folder hierarchy with shortcuts to just those VSTs you want Temper to use.
You can change the audio and VST settings at any time from Setup->VST and Audio in the main menu.
Temper is currently available as unrestricted trialware. There is no expiration, you can evaluate it for as long as you need, but if you decide to make it a part of your workflow you must buy a license, available here. Once you purchase a license, you can register when you next use the application.
