mTonal vs PaSSBot

mTonal is an expressive 24-tone keyboard synth that can be used to smoothly glide across the frequency spectrum, something which is not possible with a regular MIDI keyboard controller. It can send MIDI information to digital audio workstations (DAWs) that support MIDI Polyphonic Expression (MPE), making this app extremely versatile for recording and processing microtonal MIDI data. Record audio files using the synth presets of the app and share them across other apps, email, or social media. BASICS Explore the world of quarter-tone music using this 24-tone keyboard. Blue keys between the white and black keys mark the quarter-tones. Switch between octaves using the octave controls on the upper-right corner of the keyboard. Choose between three keyboard layouts: one octave, two octaves, and seven octaves. The seven-octave layout gives you a wide range of tonal possibilities without taking the size of a grand piano. Use the warning button to clear any unreleased touches in the synth. MIDI FUNCTIONALITY Send MIDI information to various DAWs and software synthesizers that support MPE (MIDI Polyphonic Expression) like Logic Pro, Cubase, and Max/MSP. You have the option of using a wired, Wi-Fi, or Bluetooth MIDI connection, and you can change the connection anytime using the settings button on the upper-left corner of the keyboard. FEATURES Turn on gliding to smoothly transition between two notes and create a microtonal soundscape. Use the cents button to display the note's cents value for precise control over the pitch. Familiarize yourself with the keyboard’s layout using the notes button, which displays the note names on top of the keyboard. For more expressiveness in playing, activate the velocity feature to control note velocity based on the touch size. Hold notes for an extended period of time even after they have been released using the pedal. EFFECTS Apply delay and reverb to customize the sound. These effects only apply to the app's synth presets and will not be sent through MIDI out. RECORD, PLAY, SHARE Record and save your favorite tunes to the iPad. The files are saved in .m4a format. Once recorded, the audio files can be played back in the app. The files can be shared through email, social media, or between other apps. You can also organize your audio files and delete unwanted ones from the iPad to free up space.

PaSSBot is a unique stochastic filter bank audio processor. The desktop VST/AU version of PaSSbot has already arrived in February 2020 and this iOS version is equivalent to the latest version 2.1. PaSSBot filter types are Biquad, StateVariableFilter, Ladder, SEM and Resonators. With behaviors of bandpass, Lo + Hipass, Notch and up to 64 of them in true stereo ! The user can set values of center frequency, gain and resonance of the each filter, which will be then eloborated with powerful stochastic generators ( 4 independent GENs for each filter ) with continuous or discrete probabilistic distributions but also with standard waveforms. One can set each filter parameters individually, but also distribute them in harmonic order, again the harmonic spread ratio can be set by the user or even can be modulated by a GEN. Precision DSP rendering, less than 1milisec. control rate precision. The filters can run continuously or be triggered manually. In that case, each filter will be applied an independent AR envelope with configurable random duration. Important notes : - A recent iPAD model is being recommended and also setting the host buffer size to 128 or higher greatly helps to the CPU needs which also heavily depends on the number of parallel filters being used. - The resonators can be sensitive to input signal level. - The PaSSBot manual can be found at this link. https://www.sonic-lab.com/PaSSBot_files/PassBot_manual.pdf sonicLAB PaSSBot youtube playlist : https://www.youtube.com/playlist?list=PLP0cOkraQHDYUoMG6BETTN1eGm-Kq5z0T
