SFZ Designer free

SFZ Designer is a visual sample mapping tool optimized for multiple velocity and round-robin layers. It features a streamlined workflow, assisted opcode entry, draggable key-range and velocity splits-points, and more. It supports all opcodes and directly exports to .sfz format.

Easy To Learn And Use

Aside from providing a visual alternative to a text editor, another goal of the project is to introduce beginners to the structure of the sfz format. SFZ Designer promotes a workflow that emphasizes the creation of groups and velocity layers, which serve as 'boxes' for your samples. You make the 'boxes' and then you put the samples in.

In SFZ Designer you start with one 'box'. This is the group panel.

First let's set the 'trigger zone' or what key(s) will play your samples. Just drag the handles on the pianoroll or use the key fields on the left side to adjust your trigger zone.

If you want your instrument to respond to touch pressure, then you need several velocity layers. Touch pressure or velocity is a value from 0 to 127, where 127 is the maximum pressure (loudest). By default you have just 1 velocity layer. You can add more by clicking the + button. If you don't need touch sensitivity, then just leave it at 1 velocity layer.

If the group is your 'box', then velocity layers are like 'compartments' in your 'box' where you can store your samples. Here we have 3 velocity layers.

Now that your 'box' and 'compartments' are ready, we can start adding samples. Double-clicking a velocity layer will open the samples panel. You can import a single file or multiple files at once. If you have multiple files in one velocity layer, they will be played in round-robin sequence by your sample player.

You can tweak it further by adding opcodes. This step is completely optional.

"Wait... Do I have to do it all over again with the other groups?"
No, SFZ Designer comes with a variety of options for cloning groups and opcodes, so you don't have to start over. You can just clone the group structure and import the samples.

Now it's just a matter of adding/cloning groups and mapping them to different 'trigger zones' to make a complete sfz instrument.

SFZ Designer is easy to learn and use, and enables you to build instruments with the endless possibilities of the SFZ open format.
