Free Synthesizers to Play Various Musical Instruments

A synthesizer is an electronic musical instrument that can imitate almost any traditional instrument: guitar, piano, drum, violin, flute, as well as other natural sounds. It also lets you control and change various basic aspects of sound, such as waveform, BPM, oscillator, tone, vocal, volume level, and more. In this article, we list five online synthesizers that you can use to learn and practice musical composition.

All the synthesizers in the list support a wide range of musical instruments with options to experiment with tones, voices, BPM, IFO, noise, oscillator, frequency, amplitude, delays, and so on.

WebSynths.com

We'll start with WebSynths.com, a comprehensive online synthesizer that contains a large number of features. The platform offers an extensive list of instruments and sound modes. A good option of the synthesizer is the ability to switch between modes. From the virtual keyboard (ideal for touch devices) you can control the following functions:

• BPM.
• Oscillator – Shape, Size, Frequency filter, Amplitude modifiers, Scale, LFO, Envelope, Pan, Convolver and EQ.
• Filters – Filter matrix, oscillators, frequency tracking and LFO cutoff.
• Amplitude envelope.
• Effects: compressor, distortion, modulators, delays, reverb and equalization.

MIDI.city

MIDI.city is a very simple online audio synthesizer but with advanced options. The environment modes are: Organ effects, Piano, Guitar, Chromatic percussion, Sitar, Bass, Strings, Metal, Ensemble, Reed, Percussion, Pipe, Synth Lead, Synth Lead and Synth, and virtual keyboard. In terms of effects, you have four options: Octave, hit, pattern and BPM. You can use presets or customize them yourself. A curiosity of the platform is its "Night" mode, ideal for using the Web in a dark place.

Webx0x.com

We continue with Webx0x.com. This online synthesizer has four sections (Voice) with the same features and options (Tone, Nose, Mix, Sequencer, Tempo and MIDI). This way, you can create four configurations and switch between them easily. A simple option, but with many features.

Viktor

Viktor is an open source audio synthesizer that has many features. From its interface you can configure modulation, polyphony, oscillator, mixer, noise, envelopes, filters, LFO, compressor and volume. With the options you can create custom configurations and export the library as a JSON file. The environment has more than 20 different modes that you can change easily.

TanguySynth.com

Finally, we have TanguySynth.com, another very good open source synthesizer that has two oscillators, noise, mixer, filters, filter envelope, VCA envelope, LFO, delay, metronome and octave shift. The functions on the virtual keyboard are also assigned to your computer's keyboard. The synthesizer is very powerful, but its use is only for educational purposes, because unfortunately it lacks save or export options.

The synthesizer web pages are compatible with several musical instruments that you can use to practice and generate music.
