Release Notes You are amazing! Thank you all for your wonderful support <3. Please be patient with us. If you have a bug, email: hello@audiokitpro.com Bug Fixes in this update: • Battery Saving Upgrade. HUGE Power efficiency update when not using Synth One. We implemented what we call "Smart Power". Here's how it works: Background audio and processing automatically turn off, unless Synth One is connected to AudioBus, IAA, or a host like GarageBand. That way you don't have to worry about confusing settings. It determines your workflow, and adapts for you. :) • MIDI Bluetooth connects easier • New Presets and Sounds in the "JEC" bank, including a nice Pink Floyd inspired preset ;) • Tap the circle on the "Tune" panel for more displays 4 states when you tap: 1) Harmonic approximation 2) Pitch (log2(frequency)%1) 3) Cents (1200*log2(frequency)) 4) Frequency You are all awesome! We are all volunteers building this app for you. Please spread the word! Thank you :)

Experience playing the full, lush tones of a Dusty Strings D550 chromatic hammered dulcimer right on your iPad.

New version 4.0.2
Old version 4.0.1
Release Notes Name changed to "Dusty Strings D550 Dulcimer" Bug fixes and performance improvements. The app may now be used as a MIDI sound module for use with CoreMIDI-enabled MIDI file player apps or controlled from an external MIDI keyboard using a hardware MIDI interface. When used via MIDI, the app responds to MIDI note-on (with velocity), note-off, and volume change messages on the selected MIDI channel. Select the MIDI channel on the controls page. The treble bridge volume and panning is used for all MIDI sounds and will respond to MIDI volume messages. Fixed a rare issue that may have caused the sound to stop when used as MIDI sound module in the background. Volume sliders now show a full range from 0 to 100% The app also works as an Audiobus source module.

New version 2.3.7
Old version 2.3.6
Release Notes Thank you for using PolyNome. I'm constantly working to improve the app and add new features. If you have time to leave a review, they really help. Thanks in advance! New features in this version: ● Quick Access Playlists: This feature lets you choose a selection of Playlists that you can load with a single tap directly from the Playlist (instead of going into Playlist Manager). This is particularly useful if you have songs that you play to click that require time signature or tempo changes. You can create the multi-part click in a Playlist, then use the Quick Access feature to line up all the songs you'll be playing in a show. It's also useful if you want to line up a selection of Playlists to work on in a practice session, or if you just want to have some basic Playlists easily available at all times. ● Arrange option in Playlist: This is a new option in the Actions menu when editing a Playlist. Select a number of items in the order you'd like to have them, then tap Actions and choose Arrange. They'll be arranged in the order you selected them. If you didn't select all of the items in the list you'll be give the option to arrange them at the top or bottom of the Playlist. ● Long press a Preset to bring up the Actions menu. ● Long press a Playlist item to enter edit mode. ● New 'Big Numbers' modes: Tap the 'mode' button under the Big Numbers fader in the mixer to toggle through them. ● Count-ins are no longer added to the Practice Log ● When tempo percentage slider is visible in a Playlist, the tweak buttons will change the slider value, and not the tempo. ● Improved performance with longer setlists. Long setlist names are now truncated in the centre. ● Design tweaks and improvements. Minor bug fixes. If you find any problems, or have any questions, don't hesitate to get in touch via the help page or the website. Thanks again! Joe
