Poseidon Synth vs KeepTrack

Poseidon Synth - The Ocean of Sound For all creatures in the ocean of sound - Sonic textures from other worlds, Analog signature sounds,  Cut-through-the-mix leads and silkily smooth pads: Poseidon sets a new standard for sound design and ease of use. All of this was made possible through a combination of the familiar, conceptual simplicity of the analog synthesis and our frequency domain based Spectral modelling synthesis technology. Spectral model oscillator Select a basic sound model from over hundred delivered with Poseidon. The basic sound model determines the sound characteristic you want to start: taking a artificial model like “Sawtooth” gives you analog style sounds. Use complex models from analyzed samples for earth shaking ambients and evolving pads. Model parameters High level controls allow for changing the spectral shape, the harmonicity and balances the level of residual noise and spectral amount of the oscillator model. F-Domain Filter The newly developed F-Domain filter allow for drastic changes in the resulting sound spectrum. Five filter types including lowpass/highpass characteristic can be used to shape the sound. They have the usual controls like cutoff but also very unusual ones like a variable slope ranging from 0 dB to 72 dB / Octave and independent controls for resonance and bandwidth! This kind of controls are only possible in the context of our F-Domain synthesis technology. This results in an extremely clear filter sound with breathtaking fast modulation possibilities.

The filter type “Inverse” interprets the sound model as a "Source" and a resonant body "Filter". The cutoff parameter shifts the filterbase - this is the equivalent to making the instrument body smaller or bigger. Spatializer This simple control gives your sound a distinctive moving distribution in the stereo panorama. Every atomic sound particle has it´s own path through the space !

KeepTrack: Musical Journey helps music students keep a clear, structured memory of what they are working on between lessons. Build a local library of lesson books, repertoire, and standalone titles. Track each title's status, current page, practice focus, wins, and next steps. Add lesson notes with teacher feedback, assignments, and linked books or pieces so weekly progress does not disappear between lessons. New in this version, Practice Recordings let you record yourself playing a piece and listen back later. Takes are saved with the piece they belong to and kept in a protected store on your device. Sheet Music keeps the score with the piece. Attach PDF scores to any title, read them in a built-in viewer, and open them without leaving an active practice session. The Sight-Reading Trainer gives you timed reading rounds with difficulty tiers, correctly engraved treble, bass, and C clefs, and prompts spelled the way you would read them on the page. Wishlist gives you a dedicated place for future books and pieces you want to play later. Wishlist items stay separate from your active Library until you choose Add to Library, and they can be included in a teacher report when you want to discuss future repertoire. Practice Mode gives premium users a focused timer with an integrated metronome, BPM controls, meter controls, visual beat cues, backing-track playback, session history, piece switching, and practice summaries. Reports remain preview-first, so you can review exactly what will be copied or shared. KeepTrack: Musical Journey is built for private, local-first music progress tracking: - Practice recordings saved on device with the piece, with playback speed control - Sheet music PDF attachments and a built-in score viewer - Sight-reading trainer with difficulty tiers and a progress graph - Backing-track playback inside a practice session - Instrument profiles that keep separate repertoire, history, and reports - Library tracking for lesson books, repertoire, and standalone titles - Wishlist tracking for future books and pieces - Add to Library conversion from Wishlist into active repertoire - Status labels for new, active, polishing, and completed titles - Multi-select status filtering across the library and reports - Practice timer with metronome, BPM, meter, and visual beat cues - Practice and lesson note organization, with search across saved notes - Archive and restore flows for old material - Teacher-ready report previews with optional Wishlist inclusion - A Settings hub for appearance, support, membership, privacy, and legal information - Private iCloud sync for the learner's own devices - StoreKit premium unlocks for unlimited library and practice features Your music lesson journal and sheet music are stored on device first and can sync through your private iCloud account when iCloud is available. Practice recordings stay on the device that made them. The app does not use developer-operated accounts, advertising, tracking, analytics SDKs, public sharing, or remote AI services. Sharing happens only when you choose to copy or send a generated report through the system share sheet.
