0.9b13 Release Notes
15/7/2003 AudioMulch 0.9b13 Release Notes
AudioMulch version 0.9b13 is now available from the download page. This version will expire on October 15th, 2003.
AudioMulch version 0.9b13 includes significantly improved support for synchronising to an external MIDI clock; new feedback modes for the SDelay contraption; an increased upper limit of 200 for the number of simultaneous grains in BubbleBlower, DLGranulator and Nebuliser; and includes fixes for a number of previously reported bugs. A bug in the granulators' randomisation function has been fixed, and some display anomalies have been addressed.
Bugs that have been fixed for this release are listed below.
- Fixed bug where new samples would play when switching presets that changed soundfiles in the Drums contraption.
- Fixed display problem where some number editors (e.g. Max Grains in Granulators) would only display one digit.
- Fixed bug where all random granulator parameters would be randomised in lock-step (higher transposition results in panning to the right for example).
- Fixed bug where 5Combs Frequency popup value hints obscured note number display.
- Fixed bug where some VST plugin's parameters were not correctly restored with the document.
Changes to the SDelay contraption
The SDelay contraption has been extended with the addition of a Feedback Mode setting. This allows selection between one of four feedback modes: Stereo, Ping-Ping, Ping-Left and Ping-Right. Previously the SDelay contraption was hard-wired to use the Ping-Right setting. The Stereo feedback mode essentially provides two mono delay lines each with independent feedback paths; the Ping-Pong mode uses crossed-over inputs and crossed-over feedback between the two delays providing a full stereo ping-pong effect; the Ping-Left and Ping-Right modes respectively feed the left or right delay outputs back into both inputs providing a less dense "half ping-pong" effect. Each of these feedback modes has a characteristic sound, especially when combined with different delay times for the left and right channels.
Another change which has been made to the SDelay is that the inputs are now normalled in the same way as the stereo mixer contraptions. That is, if only one input is used (either left, or right) the contraption works as if the same signal were connected to both inputs. Previously only the left SDelay input worked this way, when the right input was used alone, the left input was considered silent - if necessary the old behaviour can be reproduced by connecting a silent input to the left input of the SDelay contraption.
New Decorrelation parameter for Granulators
A bug which has been present for a long time was discovered: the method used to randomise parameters in the granulators (Bubble Blower, DLGranulator and Nebuliser) was found to be incorrect. All parameters for a single grain were correlated so that, for example, higher pitched grains would be panned to the right. As this bug had a characteristic sound, it was decided that it was necessary to provide backwards compatibility for existing AudioMulch documents. This was achieved by adding a new parameter "Decorrelation" (DCor) which allows the randomisation to be varied between the old behaviour, and a more standard behaviour where the grain parameters are totally randomised. Old AudioMulch documents will load with DCor set to zero (0 - totally correlated) which provides the old behaviour, newly created granulators will initially have DCor set to one (1 - random, totally uncorrelated).
