The for loop syntax is a way to loop through the array elements in order. By iterating, multiple files can be generated in sequence. This can be used to generate multiple single-cycle waveforms.

The above code loops through the numbers 1 through 5. When executed, it generates five sine waves from the base note to the fifth overtone in sequential numbers.

I will show you how to create a Wavetable in Octave, a numerical calculation software. The waveforms you create can be used with Serum, Ableton Wavetable, or any other audio-importable wavetable synth or sampler.

Advice

• Octave is compatible with Matlab, so if there is a function you are not sure about, the Matlab web page is also a good reference.
• In Octave, if you don't put " ;" at the end of a line, the result of the calculation will be output to the command window. When looping, if you do not put a " ;" at the end of a line, the result of the calculation will be output to the command window endlessly, so be careful.

This sample pack includes the sounds of A4 Classic Drum Sample Pack and AR Classic Drum Sample Pack, which recreate the sounds of analog drum machines like the 808 and 909.

Classic drum machine sounds for Analog Rytm
Sound patches that imitate the sound of classic drum machines like the CR-78, 808 and 909.
​
Including

• 35 Patches(BD-6, Cowbell-2, Clap-2, Clave-2, Conga-3, Guiro-1, Hihat-1, Maracas-1, Metal-1, Rim shot-6, Snare-6 ,Tambourine-1, Tom-3 )

Drum sample pack was created with Elektron Analog Four Mk1. Sample format is suitable for Elektron Analog Rytm/Digitakt/Model:samples and any other samplers that can handle Wav files.

This sample pack was created from the A4 Mod Drum Patch Pack in the patch collection for  Elektron Analog Four. The pack contains electric drum sounds and semi-realistic percussion sounds created using various modulations.
