OSD, aka OR SUM DIF, is 3 independent blocks of useful utility in 4HP.
OSD is centered around combining voltage in useful ways. Audio, V/Oct, and control voltage are at home in this utility. OSD offers a fully DC coupled signal path with precision components to make this happen. High quality, configurability, and compact size ensure OSD will always find it's way into your patch.
- Combine v/Oct sequences with precision summing, or enable the the precision OR circuit for completely different results.
- Mix two envelopes or an envelope and lfo using sum to create large accented voltages or combine with OR to keep the output in the original range.
- Crossfade between audio or control voltage using the potentiometer in block one. Setting DIF will invert the signal at the B jack.
What is OR, SUM, and DIF?
OR - Input voltages are compared and the higher of the two is passed to the output.
For example if A = 4V and B = 8V, the output will be 8V.
SUM - Input voltages are added together to create the output voltage.
For example if A= 3V and B=4V, the output will be 7V. This clips at -10V and 10V.
DIF - B voltage source is subtracted from the A voltage, producing an output of the difference between the two.
For example if A= 3V and B = 5V, the output will be 2V.
Controls / Configuration
Block 1 - Sum, OR, or Difference of two inputs and effect the mix of the A input to the B input with the Knob. The third input ORs with the result of the A/B inputs. Not a precision channel.
Block 2 - Sum, OR, or Difference of two inputs with high precision. The third input ORs with the result of the A/B inputs.
Block 3 - 3 input OR with high precision. Mix gates or CV from three sources for some wild results.
- Width: 4HP
- Depth: 40mm
- Power: 50 mA +12V / 50 mA -12V
How much is my shipping?
Shipping costs are calculated automatically at checkout. Simply add items to your cart and proceed to the checkout page, where you'll see the available shipping options and their prices. VAT at the applicable rate for your country will also be displayed at checkout.
European Union orders:
- Standard shipping is free on orders over €100. Express shipping is available on orders over €100, and free on orders over €400.
Poland orders:
- Standard shipping is free on orders over 250 PLN. Express shipping is free on orders over 500 PLN.
What about local taxes?
By default prices on the site include sales tax at 20%. The precise sales tax rate for your country will be calculated at checkout.
Do you ship to my country?
We ship to all EU member states from our warehouse in Warsaw, Poland. Add an item to your cart and enter your country and postcode to see the available shipping options and prices for your location. If you have any questions about shipping to your country, drop us an email at info@signalsounds.eu and we'll be happy to help.
Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.
Estimated delivery times (Standard shipping)
The times below are estimates in working days from dispatch, based on UPS Standard service. Express Saver delivers by the next business day to most destinations.
| Country | Estimated delivery (working days) |
|---|---|
| Austria | 2–3 |
| Belgium | 2 |
| Bulgaria | 4–5 |
| Croatia | 2–4 |
| Cyprus | 10 |

| Romania | 3–4 |
| Slovakia | 2–3 |
| Slovenia | 2–3 |
| Spain | 4 |
| 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.
