Refund policy: I only want happy customers! Should you have any issue with linotune, let me know and I'll do my best to resolve it. Should you wish to return any linotune product for any reason, just tell me so within a month of purchase. After you've deactivated your product you'll of course receive a full refund.

Buying linotune outright has the advantage that, once activated, it won't require any Internet connectivity, except when moving the license to another machine.

This optional upgrade allows you to run any number of linotune windows simultaneously, limited only by the performance of your machine. The strobes communicate via shared memory, can (but do not have to) share the same audio input and/or output, and can be slaved to run at a given interval from the first ("master") strobe. Each strobe remembers its position and configuration - so you can for instance arrange a dozen strobes as a chromatic "strobe center."

This upgrade requires that you posess:

• a valid linotune license - please enter license key below before clicking the "Buy Now" button;
• a recent Mac, or capable Windows machine - please use the free trial to verify multi-strobe performance on the target machine before purchase. A fast machine can handle a dozen strobes at a good frame rate.

You can also rent linotune for a monthly payment. This allows you to use linotune right away with little upfront cost, and to cancel the rental any time. The disadvantages of renting linotune are:

• requires that you have (or open) a Paypal account;
• higher total cost of ownership over the long term;
• linotune needs to connect to the Internet at least
  once a month to verify your ongoing rental payments.

50% sign-up bonus: when you rent linotune, your first payment will enable you to run linotune for 1.5 months instead of one. Subscribing then canceling after the first payment is thus a cost-efficient way to give linotune an extended trial, or use it for a one-off project. If you leave the rental running, subsequent instalments will then each add a month of validity to your license.

I've completed the purchase, where's my license key/upgrade? If you don't receive an email with your license key or upgrade within minutes of completing your purchase, it is most likely for one of the following reasons:

• the email got filtered as spam by your provider - please check your spam email folder for it;
• you've given an incorrect email address during the purchase - please contact me with your correct address;
• you've chosen to pay via an e-check from your bank account. You'll receive your license key or upgrade as soon as the payment clears. Paypal e-checks can take up to a week to clear; you can avoid such delays in the future by using a credit or debit card to pay, or to back up your paypal account with.

What if my installation of linotune is damaged or deleted? Your license key remains valid regardless of events such as OS upgrades. If you lose your installation, simply download & install linotune again, then re-activate it with the original key. Make sure you keep a copy of your license key in a safe place away from your computer!

Can I run linotune without Internet access? Certainly! Interaction with our server is required only for activation and deactivation (in order to move your license to another machine), and about once a month if you've rented linotune.

Can I lease the multi-strobe upgrade? Sorry, this upgrade can only be purchased outright, and for licenses that are permanent.

What if the linotune server dies? While it is not possible to buy or activate linotune when our server is down, an already activated copy of linotune will continue to run happily. Our server is housed in a highly reliable and secure professional data center; its downtime is measured in minutes per month.
