SinOscillators
Read full descriptionHide full description
SinOscillators is a strange synthesizer with nine oscillators. It uses a unique sine wave generation algorithm, resulting in sounds that are difficult to predict and control. Sometimes the sounds are noisy, sometimes eerie, but sometimes they're captivating enough to listen to for a long time. This app allows you to set and control the following: - Buffer: Size of audio buffer - Transition: Parameter transition time - Spread: Stereo sound spread - Volume: Overall volume - Shuffle: Randomly set oscillators to the same value - Clusterize: Set the oscillators to similar values - Harmonize: Adjust oscillators systematically - Mute: Temporarily silence oscillators - Slider: Set oscillator’s parameter lik a pitch - Button: Play or stop oscillators - Randomize: Randomly change parameters - Targets: The percentage of random parameter changes - Timer: Randomly change parameters at specified intervals

Your Fingertips Create New Sounds OscDrax is an innovative iOS waveform synthesizer that enables professional sound design through intuitive touch controls. Simply draw waveforms with your finger to instantly create original tones. Combine four independent tracks to build complex, rich soundscapes. Unleash Creativity with the Waveform Editor Our waveform drawing system maximizes the potential of touchscreen technology. With 512-point high resolution, accurately reproduce any waveform you imagine. Classic waveforms like sine, triangle, square, and sawtooth are also available at a single tap. Designed for everyone from beginners to professionals. 4-Track Multi-Timbral Synthesis Each track operates completely independently with its own waveform, frequency, and volume settings. Layer multiple tracks simultaneously to create thick, complex tones impossible with a single oscillator. Professional Controls Frequency Adjustment (20Hz-20kHz) Full coverage of human hearing range. Logarithmic scale slider provides musically natural control from bass to treble. Portamento Function (0-1000ms) Smooth glide effect between pitches. Faithfully reproduces the warm expression of analog synthesizers. Individual Volume Control Fine-tune each track's volume from 0-100%. Achieve ideal balance with precision mixing.

Verdict
The clearest difference is update cadence: OscDrax at daily against SinOscillators's every 3 months. OscDrax also leads on price ($0.49 vs $3.99). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
