Manufacturer’s description
The Tiptop Audio Buchla 296t module is designed to replicate the complexity of Don Buchla’s Programmable Spectral Processor Model 296, which encompasses filtering, envelope following, vocoding, and more. It incorporates 16 fixed-frequency filters; these filters all use the same inputs, but understanding the other features requires closer examination of the output sections.
There are three audio output sections: Comb Filter Outputs, Attenuator Outputs, and Programmed Outputs. The Comb Filter Outputs provide the sum of the odd and even filter bands. The Attenuator Outputs respect the front-panel level control sliders, delivering summed outputs of all the bands and the odd/even bands as groups. The Programmed Outputs (even, odd, and all) are controlled by the Program Control, Programmed Spectrum Transfer, and Local Program CV controls.
In essence, the Program Control’s frequency and width controls enable you to “scan” the filterbank and focus on specific frequency ranges at the Programmed Outputs with the option of voltage control. The Local Program Inputs are voltage control inputs that allow for more granular control of the level of each individual band at the Programmed Outputs. The Programmed Spectrum Transfer section allows you to connect the envelope follower outputs from the odd bands to the even bands’ CV inputs or vice versa. When thoughtfully used in tandem with the Even and Odd audio inputs and outputs, this enables crude but effective vocoder-like behavior.
Furthermore, direct envelope follower outputs and audio outputs are available for each band. The Eurorack format’s compact design necessitates several compromises in terms of user interface vs. the original Buchla module, but overall, the 296t fits most of the features of the original Buchla module into a format that is more accessible to many musicians. It will be a welcome addition to any 200t system.

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 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.
Shipping to mainland EU typically costs between £7 and £20, depending on the shipping method and the size and weight of the order.
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, Royal Mail and Parcelforce for the UK, and for international orders it's either DHL, FedEx, UPS, Royal Mail or Parcelforce 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 aim to 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.
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 shipping
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
Since April 2020, the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer. There is absolutely nothing we can do about this, unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
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.
