The Cali oscillator is a new and improved version of the classic Buchla 258 wave shaping oscillator with an additional pulse width modulated output. The oscillator features the classic Sine to Square and Sine to Saw wave shaping with dedicated CV control.
The Cali Oscillator differs from previous versions of the 258 in that it has a 3-way position switch rather than 2-way. This new middle position features a bonus waveform that will shape from a pulse into a kind of triangular trapezoid shape. The shaping control is more unpredictable in this middle position and the switch reacts to body contact when the wave shape is set low – it can be thought of as an extra bonus waveform, great for producing glitchy sounds!
There are dedicated inputs for linear and exponential FM and the Cali also adds a Pulse output with its own width control and PWM CV input. The behaviour of the pulse output can be affected by the position of the waveform switch and wave shape control.
The module features Coarse and Fine frequency controls and an LFO mode. LFO range is accessed via an LED pushbutton that also acts as the LFO speed indicator – the button will light up when the waveform moves through its positive cycle.
Because the wave shape modulation is independent of pitch this oscillator is very useful for creating complex timbres whilst retaining musical pitch.

- Includes power supply isolation on frequency controls
- Width: 12HP
- Depth: 20mm
- Power: 38 mA +12V / 34 mA -12V / 0 mA 5V

| Sweden | 3–5 |
These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
