V.A.S.T. Capabilities, Infinite Creativity
We asked ourselves, what if we could rebuild the legendary K2000 V.A.S.T. synthesizer, but using today’s technology? Enter the new K20 Series…
From the world renown R&D facilities in Waltham, MA, the K20 Series represents the culmination of Kurzweil’s 30+ year evolution of V.A.S.T. technology, perfected through generations of venerable K2 synthesizers. With 32 customizable layers per program, massive polyphony and a host of creative hands-on controls, the K20 Series empowers you to craft expansive and nuanced sounds ranging from V.A.S.T. classics through yet unheard of soundscapes.
The K2061 V.A.S. T. synthesizer combines modern industrial design with a deep factory sound library of over 2000 Programs and over 500 Multi combinations organized into 13 instrument categories featuring many legacy K2 era synth-forward selections.
Dynamic V.A.S.T.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK, 'next working day' shipping is free to most parts of the UK if the order value is over £150, and £5 otherwise. We can also ship on a 'next working day before 12pm' service, which costs £6 for orders over £150 and £7.50 for orders under £150.
Certain areas of the UK, including the Scottish Highlands and Islands, Northern Ireland and other offshore islands, may have higher shipping charges and slightly longer delivery times due to surcharges applied by the courier and reduced service availability in those areas. We try to keep these costs to a minimum.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of DPD and Royal Mail for the UK, and for international orders it's either DPD, DHL, FedEx, UPS or Royal Mail depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 16:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
Please note that 'next day' delivery is an aim, not a guarantee. The vast majority of orders shipped on a 'next day' service do arrive the next day, but occasionally couriers experience unforeseen delays due to weather or traffic conditions etc.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes the couriers may come to collect a little earlier than scheduled which would also push an order into the next day.
Saturday/Sunday delivery
If you're in the UK and you order before 16:00 on a Friday then we can send something for a Saturday or Sunday delivery with DPD. This is FREE for order values over £350, £5 for order values between £75 and £250, and £7 for order values under £75. (NB: this applies to UK mainland addresses only). Please note that any orders placed after 16:00 on a Friday will ship on the Monday.
International shipping times
Most orders are delivered within 3 to 5 working days if sent on a courier service. Royal Mail services can take a lot longer and are often less secure.
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 if you have questions.

Certain areas of the UK, including the Scottish Highlands and Islands, Northern Ireland and other offshore islands, may have higher shipping charges and slightly longer delivery times due to surcharges applied by the courier and reduced service availability in those areas. We try to keep these costs to a minimum.
