If you feel the app is missing an important feature or tool, please let me know and I'll put it on the TODO list for the next major version. I can't guarentee that all the features will be added immediately, or at all, but I'll do my best to integrate the most useful suggestions. And feel free to voice your opinion on the suggestions (without being agressive or insulting) to support them.
Marc made an excellent recommendation regarding volume in the app. He commented that some of the instruments were very loud. This is a serious safety concern. Some parameters in the app (like filter settings) can produce resonances or feedback that get very loud. If this happens when you are using earphones or headphones, your hearing is put at risk.
So, as of version 1.08, an audio limiter is enabled in the app and a warning about protecting your hearing is shown on startup. The limiter can be disabled in the settings menu, at your discretion, but it should not interfere with normal use of the app at moderate volume levels.
Please be careful and protect your hearing.
Marc also asked if notes could be set to play longer or shorter without having to change instruments.
Traditionally, the duration of each note is interpreted as the sustain on each note. Many DAWs show this on the piano rolls as rectangular bars. This is not the same philosophy as tracker based sequencers, from which Oscalate draws inspiration. Trackers notes were originally triggered events to turn on a sample and play the sample until it reached the end of the sample or was stopped. As trackers became more sophisticated, looping was introduced to produce notes of variable duration.
I agree with Marc and often find that I would like some notes to sustain longer than the instrument is configured for. However, this will require some thought and planning to implement and integrate into the grid sequencer.
For the moment, we will have to wait a little bit longer for this feature.
