FontStack is a 'fontastic' new AUv3 plugin for iOS which can be loaded into your favourite DAW allowing you to utilise all those wonderful and nostalgic SF2 SoundFonts you've collected over the years. The SoundFont standard was created back in the early 90s, and made famous by the SoundBlaster series of sound cards. With the introduction of the Amiga, it spawned a host of musical creation tools called Trackers, which allowed the Amiga to load these SoundFonts and create sophisticated musical scores of 4 or 8 tracks. These days we don't use this standard so much, but there is a wealth of free SF2 files available on the internet just waiting to be loaded into FontStack. A SoundFont comprises a file with an .sf2 file extension. This file contains a set of samples, instruments, and presets. FontStack enables you to load one or more SoundFonts into its 4 layers, and use them in lots of creative ways. You can stack layers to create a rich combination of multiple tones, or assign each layer its own key range on the keyboard to create virtual splits, or a mixture of the two. Each layer can also be assigned its own MIDI channel for true OMNI mode. One great feature of FontStack is its ability to cache all your SoundFonts and the instruments they contain. This allows quick searching for specific instrument types without the need to physically search through SoundFonts to find them. Another great feature is the ability to optionally link to a remote folder containing a global set of SoundFonts, so that they can be shared between apps. Both internal and external SoundFonts and their instruments will be cached and searching is just as easy as it is using internal SoundFonts. FontStack features: ○ 4 SoundFont Layers which can be stacked, layered or played on different channels. ○ 6 Scenes per Layer containing different SoundFont instruments and settings. ○ Keyboard Splits can be created spreading multiple SoundFonts over a single keyboard. ○ SoundFont Stacks can be created, stacking multiple SoundFonts to produce a bigger, thicker sound. ○ Disk Streaming allows you to stream a SoundFont directly from disk saving physical memory. ○ File Manager allowing local and remote file management. ○ Symbolic Link allows you to specify a remote/external folder from which to access your SoundFonts. ○ Instrument Search allows you to search the content of local and remote SoundFonts folders. ○ Drag and Drop your sound fonts directly into the SoundFont Manager. ○ Reverb, Delay & Chorus effects can be applied to each instrument layer. ○ Haas and Stereo Width can be used to simulate virtual STEREO on SoundFonts with MONO samples. ○ Allows direct control of the SoundFonts Amp Envelope and Filter settings.
VibeTempo

Feel the beat. Silently. VibeTempo turns your Apple Watch into a vibrating metronome: the tempo goes straight to your wrist, with no sound to fight your instrument or bother anyone around you. No second gadget to buy, charge, or strap on. You already wear your metronome. HOW IT COMPARES Most watch metronomes stop the moment you lower your wrist. VibeTempo keeps vibrating for up to an hour with the screen off, and keeps going when you raise the watch again. Many others tap so softly you lose them while playing; VibeTempo's taps are firm and distinct. Some make you drag a slider to find your tempo; here you dial it exactly with the Digital Crown. And several charge a subscription or unlock features one by one; VibeTempo is complete the day you buy it. EVERYTHING INCLUDED, PAY ONCE No subscriptions. No accounts. No ads. Buy it once and it's fully yours, forever, updates included. WHY VIBETEMPO • Firm, distinct taps, tuned so you actually feel them while you play • Keeps vibrating with the screen asleep or your wrist down, up to an hour per session • Works on the Watch alone, no iPhone nearby needed • 30–240 BPM: dial the exact tempo with the Digital Crown, or fine-tune with − and + (no fiddly sliders) • Tap tempo: tap the rhythm and VibeTempo locks onto it • Accents your way: touch any beat of the bar to make it strong, normal, or silent • 12 time signatures: 2/4, 3/4, 4/4, 2/2, 3/8, 6/8, 9/8, 12/8, 5/4, 5/8, 7/8, 7/4, with a distinct strong downbeat • Subdivisions: eighths, sixteenths or triplets, matched to each time signature • Remembers your tempo, time signature and accents between sessions • Classic tempo names, Largo through Prestissimo Built for musicians: drummers who can't hear a click over their own kit, guitarists in rehearsal, conductors, dancers. Also a quiet pacer for runners and walkers, and some people simply enjoy a steady, gentle pulse on the wrist. MADE BY A DRUMMER, NOT A MEGACORP I'm César Pedreros. I built VibeTempo because I wanted to feel the click instead of hearing it, and nothing out there felt right on the wrist. No giant company behind this, no subscription: just a drummer selling you an app for the price of half a coffee. If it helps you keep time, a review helps me keep going.
