Analog and Trigger Sequencer, 2 rows of 8 steps with knobs and 2 rows of 8 steps switches

Features of the analog rows (knobs):

  • 8 potentiometers (knobs)
  • lower row: Scale (knob), voltage output range 0 ... ~ +6,5V
  • upper row: 1V/2V/4V (octave range switch for exact VCO control), voltage output ranges 0 ...1.0V / 0 ...2.0V / 0 ...4.0V
  • Glide time (knob), same as portamento or slew limiter
  • Glide Control (control input for switching glide on/off)
  • S&H Control (control input for internal S&H, works like A-148)
  • Pre Glide/S&H-Out (analog output before S&H and glide unit, especially required when external audio signals are used as inputs of the lower row)
  • Post Glide/S&H-Out (analog output after S&H and glide unit)
  • lower row: external inputs for the 8 steps (switched jack sockets), control signals or audio signals may be used as inputs (allowed voltage range -5V...+12V), the knobs of the lower row are working in this case as attenuators

Features of the trigger rows (switches):

  • 4 Trigger/Gate tracks with 2 rows of switches
  • toggle switches of 1-0-1 type (with middle position), which can be used to send a trigger/gate to the track above or below or to send no trigger/gate (middle position)
  • 3 trigger rows (i.e. short pulse for each step set, pulse width corresponds to the pulse width of the clock/step input signal)
  • 1 gate row (i.e. a high signal is applied during the length of the step set)

Control inputs and buttons:

  • Step (defines the tempo of the sequence, same as clock or trigger input)
  • Reset (resets all rows to step 1)
  • Start (starts the sequence at the momentary position)
  • Stop (stops the sequence at the momentary position)

Step and Reset are compatible to the MIDI interface A-190, i.e. in combination with the A-190 the A-155 may be synchronized via MIDI. The quantizing module A-156 can be used to quantize the infinite analog voltages coming from A-155 into discrete semitone steps (multiples of 1/12V). Without MIDI interface e.g. a LFO rectangle output can be used to define the tempo of the sequence.
The sequencer controller A-154 adds a lot of new functions to the A-155 (e.g. voltage controlled addressing, forward/backward/pendulum/random mode, voltage control of first and last step, voltage controlled clock and gate length, step skipping, combination of several A-155 in parallel/serial mode and many more).

  • Width: 50HP
  • Depth: 40mm
  • Power: 80 mA +12V / 20 mA -12V / 0 mA 5V

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.

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.
