Fundamental is a sound synthesis software combining the different roots of electronic music history. Its wave engine is a faithful sonic recreation of a vintage Rohde&Schwartz vacuum tube oscillator ( having been widely used at WDR by Stockhausen ) Thanks to sonicLAB audio engine design, Fundamental leaves behind the limitations of the original device by proposing complex modulation possibilities, stochastic distributions addressing the sonic parameters like frequency , gain, stereo panning etc. in continuum, which has not been applicable until now. The Fundamental software presents you 8 instances of this vintage sine wave generator with all the artifacts and richness of a vintage equipment. That combination is we believe something you should experience. Direct Link for manual : https://www.sonic-lab.com/Fundamental/Fundamental2iOS_manual.pdf Fundamental2 brings following new features to the Fundamental1, basically now you can create organic, endless moving textures. (for iOS standalone and AUv3 ) - Ring Modulator, 7 individual modulator oscillators and one carrier oscillator. - A morphing engine which lets you gradually morph between four instances of Fundamental scenes. Also a stochastic manipulation on the 2D morphing panel is possible. - True real time gradual transition between tuning scales. - Rotary Encoder midi controller mapping for high resolution oscillator frequency and gain control with midi hardware. - One can send midi note-on messages to each Fundamental oscillator on discrete midi channels. - A morse code simulator is available on each GEN (sonicLAB LFO design ) which can create custom morse signals to modulate the relevant GEN outputs. - new envelope type "Ernd". Whether you play live electronics, compose for media or just insterested in early electronic music, Fundamental2 is a strong tool. Some of the main features of Fundamental1: ( iOS standalone and AUv3 ) - unique polymorphing wavetable synthesis without any compromise in data content and precision. - 4 dynamic wavetables being rendered for each voice to represent infinitesimal steps of frequency and gain combinations between 1HZ – 3800Hz of the original vacuum tube oscillator. - 8 simultaneous voices each with custom freq, gain, boost, panning and modulation settings. - Custom or harmonic frequency distribution of voices with variable spread ratio and tuning table. - 4 independent stochastic modulations for each voice (32 in total) addressing all parameters with various continuous, discrete distributions and also standard waveforms. - Full MPE support with various configuration possibilites. - Independent Attack / Release envelopes for each voice with various modes, AR times can be set to degrees of randomness. - Vintage oscillator or pure sine wave mode. Recommended iPAD model : A12 processor or higher. Due to screen size challenges, iPAD Mini models are not recommended.

Features
Read full description

FuncBud is an AUv3 MIDI sequencer app that generates sequences using simple math functions. You can create math functions with the function builder, then chain and repeat them to create complex sequences. A simple x + 1 function would sequence all the notes in the scale in order. It gets more interesting when you use different formulas and chain them. The sequencer starts from the root note and evaluates the first formula to calculate the new note. Then, it moves to the next formula. If it's a repeating function, it repeats the specified number of times before moving to the next formula. The formula's result is converted to a note in the working key and scale, within the defined minimum and maximum octaves. This new note is then played. Additionally, the result is stored in a history of up to 64 entries for later sum or product calculations The function builder lets you create functions with simple addition, subtraction, multiplication and division operations as well as square, square root, sum and product operations. You can also use parentheses to prioritize the calculation order. The newly created function will be saved and accessible in the library across both the standalone app and AUv3 instances. With the conditional functions, you can specify a condition like "if this function is greater than that function, then execute the function A, otherwise execute the function B". The random function generator will generate a value between two functions, a function for the lower bound and another function for the upper bound. The sequencer picks the notes in the current key and scale, between the minimum and maximum octaves. You also have a root note, the starting note, which are all defined at the top of the UI. You can use BrainBud to change the key and scale as well. The sequencer speed (rate), gate length, gate length variety, velocity, velocity variety and swing parameters are accessible with the sliders at the bottom of the UI. In edit mode, you can change the order of the functions. You can also delete a function in edit mode, or simply by swiping it to the left. Newly created patterns automatically copy the current one, making subtle changes easier. If you prefer a clean slate, you can quickly clear the list with the clear button. The loop detection function is accessible in the settings menu. When enabled, it would detect the loop and increment the 'x' value by 1 to break the loop. Please note that FuncBud is a MIDI app. The standalone version has an optional internal synth where you can enable or disable on the settings menu. The AUv3 plugin requires an audio app for output. For the AUv3 functionality, it needs to be hosted within an app such as AUM, Loopy Pro, Cubasis, Logic Pro, Nanostudio, Drambo, or apeMatrix.
